[Q] Help: GT-P6210 not detected by W7 32 bit Enterprise at all.

Hi,
Quick background: Former sys admin with some Unix experience. Already own a Toshiba Thrive rooted with CWM. Gave that to the wife and got me the GT 7+. Read the forum here prior to buying. Rooted on day one.
Stats: GT-P6210 Build: HTJ85B.UEKL1 P6210UEKL1
PC: Windows 7 21 Bit Enterprise SP1
Kies: Kies_2.1.1.11124_17_6
Later on the first day, after installing aps, I installed latest version of Kies and plugged it in with the supplied usb cable in order to transfer some files to my Sandisk 32Gb microsd. Kies already running and debugging off as per the instructions. Results: Tab plays a notice and I see the MTP connected icon. My pc does NOTHING. No sound, no notice, Kies does nothing.
I unplugged and tried the other 3 ports. 2nd port gives me same result and on the 3 & 4 port I lose the tab's MTP notice and it begins charging.
So, this is what I have done in order:
1. Re-installed Kies--->same result. No MTP notice on tab.
2. Debugging on--->same
3. Tried in on my room mate's W7 machine---> Alas! I get a driver installation and I am able to see both drives. I quickly unplugged and thanked him.
4. Cleaned my pc by:
a. Deleting all USB controllers
b. Deleting all USB installations on registry (HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumUSBSTOR)
c. CCLEANER the whole system.
d. Turn off. Pull off battery. Press power button to drain motherboard.
e. Restart and re-install USB controllers.
f. Restart again.
5. Plug in again--->Tab plays a notice and I see the MTP connected icon. My pc does NOTHING. No sound, no notice, Kies does nothing.
6. Pull my hair, bang my head, wished I would have kept the Thrive. (just plug, and drag and drop)
Left it plugged to the pc overnight. Next morning I see the found new device on systray and it is trying to find drivers. I quickly open Kies and see some activity as it tries to connect. and after a few seconds, it stops. Result: No drivers installed, no Kies recognition, no drive letters, nothing.
8. At this point I ask my room mate to let me plug in on his pc to see if he still sees it and nothing happens on his pc.
9. I wipe the table back to stock.--->Tab plays a notice and I see the MTP connected icon. My pc does NOTHING. No sound, no notice, Kies does nothing. Then after I tried other ports, it begins charging and I lose the MTP notice.
10. I re-roo,t reconfigure the beast, and do a backup. Tablet is running smooth as silk, but it never connects. This all happened in the last three days.
11. Last thing I did, as I am writing this with the tablet plugged in to the pc and MTP notice on, was to un-mount the microsd and remount. MTP re-initializes and it does nothing.
I may be suspecting a cable and unfortunately, I am in no position to get my hands on another one in a timely manner. At this point, I could reflash back to a stock firmware, send back to amazon and wait for another one to come in three to four weeks (I am deployed to a remote area) and I just don't want to do that.
The tab runs great. Love the size and speed. I guess I can continue taking out the microsd card out every time I want to add a file, but I am afraid that it may eventually end up ruining the card and possibly the tablet.
Please help. I have scoured the internet, but all I ever find is solutions that I already have tried.
Thanks in advance,
Sal

you could use adb over wifi.. There are a few apps in the market for this. Does adb recognize the tab when its plugged in via USB?
Also try Android commander, it is a GUI based adb server, you should be able to navigate to sdcard/extstorages/ and your external card should be there

You could also use a file explorer like Root Explorer and Dropbox to transfer files back and forth.

Have you tried a different USB port on the PC? like one round the back.
Also, try without the sdcard in.
Ticked/unticked USB development/debugging on the tablet?
If it works on another computer though it would suggest its your own PC which has the problem, not the tablet.
tried with Linux on the same PC?
Does Odin see the tablet when in download mode?
if you have clockwork mod recovery, doesn't that have a USB mount option ? It does on my gs 2. My tab isn't with me to check.
Oh and kies has an option to reinstall the driver. Did you try with the older version of kies again?

I'll try adb. I will install it and see if how it works. Time is tight so I will report later.

I have done all that you mentioned with the exception of Linux and Odin. I am not going to get into Linux as that would start a whole other project. I will install ADB to see if I can force the drivers.
I just tried the CWM mount USB mount but get "E: Unable to open ums lunfile (No such file or directory)"
Also, on my friend's pc worked once but not after that.
I will continue to explore the ODIN suggestion.
Thanks,
Sal

I use ES Explorer (wonderful app!) now. My end-state is not to have to remove the card every time I transfer a file.
Sal
EDIT: Sorry, I see now the dropbox suggestion. Yes that would work for smaller files, but I am not sure that dropbox can handle movie size files. It would be a last resort solution.
Thanks,
Sal

Adb is probably going to be your best bet. It can be a pain to set up at times, but in the long run is a must have for any Android device. Kies normally installs the drivers that adb uses, so hopefully you can get them to install. If it still doesn't work I would suggest swapping it out for a new tab, as much as that sucks. If you need help, I constantly check these forums, so I should be able to provide some support

Well, got ADB installed and running. Set the path and ran it. Plug the tab with debugging clicked on, and got "MTP connected" on the tab's screen. At this point I am excited since I never seen the "MTP connected " on debug mode. I typed the "adb devices" command and got "List of devices attached" ___________________.
Yep, blank. Obviously the pc is not seeing it. My conclusions are the following:
1. Bad cable
2. Bad device
The fact that it recognized once on my room mates' pc and then none at all, and the fact that it was recognized on my pc for a brief random time, then it means that the device can't handshake with the motherboard and thus is a communication issue.
I'll try my luck with Samsung tech support and see if they can replace the cable.
Just thought of something, would installing Windows XP Mode under a Windows Virtual PC recognize new devices or just feed from the Windows 7 library?

Hmm, that is strange.. I was new to samsungs and when I tried to root it it took me a while because I didn't know that kies installed the drivers. After I installed it though adb devices showed my tab connected...

I placed the tab on download mode and queried it from adb and got nothing. I then queried it via ODIN3 and got no response as well.
I have come to terms that it has to be the device or the USB cable. Just ordered two (yes, two) different type cables to test out the theory. If they don't do it, then I am sending the tab back to Amazon.
It takes about a week to get stuff shipped where I am at so I'll check in later and report.
Sal

Just an update.
I bought a cheap cable from Amazon for $ 3.31 US to test the cable theory and guess what? It worked.
Curse you Samsung for your lack of QC with your cables. I have read throughout most of the forums (not just this one) and it seems that cables for these devices are notoriously finicky.
While on the one hand, I am glad that I got a cable that works, Samsung owes me over thirty hours of my life that I had to spend on troubleshooting a brand new device.
The part that I hate the most is that when I tried to contact Samsung's tech support, all they kept telling me is that it must be my pc even after I told them all the troubleshooting that I had done. Yes, they played the blame game.
My Toshiba Thrive worked right out of the box with a standard micro usb cable.
Ok. Rant off.
Sal

Glad to hear you got it working. Personally I have a ftp server set up on my comp that I use to transfer files back and forth. Much easier IMO than having a cable every time I need something transferred

Windows 8 is not the problem, what you need are Asus drivers.......

Is there anybody who have the drivers?

It took several goes for me to get the drivers installed.
I don't know if you need to start sync too - if so, do so from the tablet's settings first.
You might also need to experiment with the storage settings and remove an SD card if you have it mounted
Google for Connect Asus to PC and similar terms.
It does work, I promise.
PS
Try Airdroid app if you want to connect wirelessly and not via USB cable

I did make Asus sync Ok in the settings, and i installed it on the computer. It finds my tablet and it's possible to sync contacts and calender, I think. But I can't the the drivers to work the Mtp has a yellow warning sign! And when I try to update the driver it fails. I've uninstalled it to, still nothing works..

Are the drivers actually installed? You need to select the tablet when connected to the PC and make sure that the drivers are installed. Under Device Manager, under portable devices (while Transformer is plugged in), you will see Transformer. Right click it and choose to update driver manually. Choose the location where you unzipped MTP folder of the download. This should update the windows driver then.

FOR EVERYBODY OVERLY [SOMETIMES SICKENINGLY] FAMILIAR WITH WINDOWS MANUAL DRIVER INSTALLS, HERE'S WHERE THOSE MTD DRIVERS ARE PUT BY THE ASUS SYNC FOR WINDOWS XP DOWNLOAD:
C:\Program Files\ASUS\ASUS Android USB Drivers\MTP
FOR EVERYBODY ELSE, READ ON:
Hey, had the same issue here, thinking it was the fact that ASUS is showing nothing past XP under their Windows downloads, so maybe a compatibility issue with their Sync setup (primarily, not copying the MTD drivers to the correct place during setup).
Having had MUCH WORSE issues with my fave little ol' Sansa Express MP3 player years ago when its battery died completely, I cracked my knuckles, sighed, and dug in for a long haul.
Luckily, I tried this first, since dealing with Windows version compatibility is much more common, so more familiar/easier.
(Of course, I was doing something different, but I'll be doing what you're doing, soon enough).
Download ASUS sync for your tabbie here:
https://www.asus.com/Tablets_Mobile/ASUS_Transformer_Pad_TF300T/#support_Download_17
Of course, it puts everything where it should, except the very important MTD files--but obviously ASUS included them--for me (32-bit Win7), they were HERE:
C:\Program Files\ASUS\ASUS Android USB Drivers\MTP
Plug your tablet to your PC via it's USB cable, wait for the Windows driver search to appear, then tell Windows to 'skip obtaining driver software from windows update'. Let it fail (that's where some of the best stuff begins!)
Go to Control Panel, Device Manager...open it.
As with some of the worst driver issues I've seen, I didn't see anything other than a single driver there--'ASUS Transformer Pad TF300T'' (see pic)--so I clicked 'Action' up top, then 'Add Legacy Hardware' (single-click something in the lower driver listings to enable this option), then 'Next', then 'Install the hardware that I manually select from a list', then 'Show All Devices'.
You don't have to wait for this list to populate--just click 'Have Disk', then 'Browse', then find the proper ASUS MTD driver at the location I described in this line above-->>>C:\Program Files\ASUS\ASUS Android USB Drivers\MTP
These will be annoying click-out submenus, but be patient--you're almost done.
Click through the rest, and you're done...NEARLY.
As is typical with this manual driver stuff (esp. storage drivers like this), I had to restart my PC to finish this driver install (and 'yes', I really did try and cheat Windows out of another 10 minutes of MY LIFE by running the ASUS Sync program on my PC, but it didn't work until rebooting).
Spoiler alert! (Upon reboot, it worked)
[ahem]
Upon reboot, it worked. I ran ASUS Sync, and [finally!!!] am seeing it recognized my tablet as what it is, and life began again after my millionth+6 Windows driver issue. (PLEASE remind me to personally 'thank' Bill G. wherever I see him after death).
EPILOGUE:
Why ASUS failed to update its driver update page after Windows XP, I'll never know, this being a little harder than the ole 'Compatibility Mode' install route...but this worked for me, and despite this little stutter-step, I'll be reaping whatever benefits ASUS sync gives me, but honestly, it wasn't even what I needed to back up my Home Page settings on my TF300T in order to factory reset the thing, because, like some here, mine is performing MUCH slower than it should, even in Performance Mode (but, hey, I got mine from a local pawn shop, so--that's expected, y'know).
ENJOY! Hope this helps, most of the time I feel I've nothing to contribute here...XDA is WAY over my wittle head!
What's really odd is that, even after doing all this, my Device Manager driver listing for the tablet still looks like the attachment I posted here, yet the thing appears to be working fine. Double-clicking on the 'kicked-out' drivers shows 'Device Failed to Start'...this is probably because Windows isn't actually using the ADB and MTD drivers until immediately upon running the ASUS Sync application, though.

I've tried all of this. But still I cannot get Sync to work. In my 64-bit Windows 7 device manager I have it listed as portable device.
I can copy files to and from it in my Explorer. I have no devices that have not been properly installed anywhere in my list. So what to do now?

[Q] Trouble connecting Nexus 5 to new laptop in MTP mode

Not sure how many would read such a long post for a question, but here goes...
Any help is appreciated!!
1. Problem
In short, I plugged in my Nexus 5 to my laptop in MTP mode, it does not show up in "My Computer".
I just wanted to transfer files to my phone via USB, not even using ADB yet.
I have yet to solve the problem after googling around for a bit.
Relevant XDA threads that I remember reading are this, this, this, this and this.
I have tried numerous combinations of (un)plugging my phone / (un)installing drivers / rebooting my laptop and phone / switching usb ports / turning USB debugging on and off / connect in PTP mode / ...
As a workaround, I am now transferring files using the AirDroid app, which is really convenient with acceptable speed.
Still, it would be nice to know why the problem occurred and see if others have similar problem.
Below I will describe the devices I have on hand and more details on the failures I have encountered will follow.
2. My Devices
A. an old Galaxy Note
B. the new Nexus 5 with the stock micro USB cord
C. new laptop
- 64-bit Windows 8 Pro (not upgraded to 8.1 yet)
- only USB 3.0 ports
D. old laptop
- 32-bit Windows XP Home
- only USB 2.0 ports
3. Details
Scenario A. Nexus 5 not showing up in "My Computer"
Naturally, the first thing I tried is to simply plug my Nexus 5 in to my new laptop. I was used to Android devices working just like that!
However, my Nexus 5 does not show up in "My Computer" after a loooong wait.
On a closer look, my Nexus 5 (only) appears in the "Device Manager" under "Portable Devices" as "MTP USB Device".
It shows my device to be "working properly". However, I cannot uninstall/disable it when my phone is plugged in (normal?)
Frustrated, I decided to unplug my phone. I have the option to "Unplug Nexus 5" under "Safely Remove Hardware", but the operation always times out, so I simply unplugged it.
Then I tried with my Note using the same cable. It works flawlessly either in MTP mode or Mass Storage mode.
Scenario B. Nexus 5 shows up, but is really sloooooooooooooow
At some point, I turned on USB debugging.
With USB debugging on, my phone appears under "Portable Devices" as "Nexus 5" (and in some other places according to what drivers I have installed).
I was quite pleased for a few seconds as my Nexus 5 now shows up in "My Computer"!
However, it took a few minutes to list the folders I have under my phone's internal storage.
Attempting to copy a 12MB file to it gives an estimated time of over 2 hours.
Scenario C. Success?
After tinkering with it for some time to no avail, I was beginning to worry if I have gotten a defective hardware.
Then I remembered I had an old laptop stashed somewhere, so I tried connecting my Nexus 5 to that.
And... voila! It works without a hitch (MTP mode, USB debugging off).
A maybe useful note is that I have used both the old and new laptops to transfer files to my Note before.
4. Possible causes
While many seems to have solved the issue by simply unplugging and letting Windows reinstall the drivers, I have no such luck.
I sincerely hope that it is not due to any hardware defects since
a) my Note can talk to my new laptop through the same micro USB with no problems, and
b) my Nexus 5 can talk to my old laptop.
I feel that this is a driver-related issue but I am not sure.
Is it possible that there are compatibility issues with using USB 3.0 port (which should be backward compatible...) or a 64-bit Win 8 Pro?
Any help is appreciated!

It is so strange..
I just bought a USB 2.0 hub and connected my phone to my new laptop through it.
Guess what... it works perfectly!
Apparently my problem was that my new laptop only had USB 3.0 ports for me to test on?
Doesn't make sense... thought 3.0 is backward compatible and my old Note works on it!
Maybe I'm missing something but I'm happy it is solved for me now

This solution worked for me. Go to http://forum.xda-developers.com/showthread.php?t=2512549 and see post #5. Be sure to thank n7of9 for the link and WugFresh for his toolkit solution. Enjoy.

Hey,
I basically seem to have the same problem as you do.
My laptop also only has USB 3.0 ports and Windows 8.1 Pro 64-bit installed.
The Nexus 5 doesn't get installed, in MTP mode it is just shown with the yellow exclamation mark in Device Manager. Downloading different USB drivers including Google's and trying to manually install it doesn't work at all. I specifically checked that all older similar drivers are gone, so I doubt that older Android devices could be interfering.
On the other hand, as you noted, using an older computer with USB 2.0 works perfectly, I had the same result.
To be honest, I'm not much of a developer or Android tinkerer, so I'm not really making any progreess... In the end, I think I will follow your example and test it with a USB 2.0 adapter.
Did you manage to get it to work without this workaround?
Kind regards! :fingers-crossed:

I'm using Linux Mint. Just plug the Nexus in. It shows up as a folder. No hassle

On the other hand, as you noted, using an older computer with USB 2.0 works perfectly, I had the same result.
To be honest, I'm not much of a developer or Android tinkerer, so I'm not really making any progreess... In the end, I think I will follow your example and test it with a USB 2.0 adapter.
Did you manage to get it to work without this workaround?
Kind regards! :fingers-crossed:

I had a lot of issues with my S3 and my work computer (windows XP SP3) and it was because I had half installed some USB driver that windows tried installing.
I fixed the problem in device manager by manually uninstalling EVERY SINGLE USB DEVICE attached to the computer while I had my phone plugged in.
Word of caution: You'll probably uninstall your mouse/keyboard doing this.
Once everything was uninstalled I reinstalled the Samsung drivers and it worked fine.
The same computer only required me to install the Google drivers for my N5. If I enable USB debugging, I all of a sudden can't install MTP drivers, but USB debugging disabled works fine.

USB & MTP mode
I have the same problem with my Nexus 5. The only workaround to transfer files to my phone from a computer via USB cable is to enable USB debuging, set the phone to PTP mode instead of MTP and then it shows in My Computer as a camera. I can only access the DCIM and Pictures folders but for now I have to settle for this...I copy all the files I need to let's say Pictures and then using a file explorer (on the phone) I cut and paste them to the folders I wish...e.g. movies to Movies, music to Music and so on...

I had same problem. Developer Mode...USB Debugging ON worked.

I have this problem too, but I got it to work using a galaxy s3 cable. for some reasons the cable that came with N5 did not work.

Its usually just missing drivers.. You can get them straight from Google or a toolkit as mentioned! (P.s you need to download a little applet like thing from Google if you want to hook up your Mac to your n5)
See andoid.com/filetransfer for the drivers.

This worked for me when all else failed: http://forum.xda-developers.com/showpost.php?p=35854664&postcount=7
Hope that helps!

The problem I am having now connecting is that my phone got wet recently. I dried it immediately and used dessicant to withrow the water and now it works (sort of). Now when I plug my phone into my pc, the usb debugging icon doesn't even show up.
I tried connecting to both my work pc and home laptop and they both say the same thing, that the usb device has malfunstioned and that windows doesn't recognize it.
Is it time for a new phone?

Sounds like the usb is shorting. How long did you let it dry. Give it more time and try it again.

Yeah maybe thats what happened. It's been drying now for about a week. The screen was the major problem at first but has since dried there mostly.
Hopefully it will come back. Would suck to have to buy a new phone because of that.

MTP connecting problem solved
Going back to the subject of the thread: I am pretty sure that ADB drivers and SDK (I am confident that a lot of nexus users have their devices rooted and that means they must have the above installed) is what is causing some sort of conflict when trying to connect the Nexus 5 as MTP. After I reinstalled the windows (W8) on my computer and connected my Nexus 5 it took @1-2 minutes to auto install the drivers and then worked fine...I have no ideea what happens if I install ADB and SDK again...

If you tell the SDK not to install the drivers it'll be fine

The simplest and shortest way to connect google nexus5 with PC as MTP(Media device)
When I plugged it, there wasn't any yellow exclamation mark within Device Manager. So for me, the drivers were OK. But the device was not listed within my Eclipse DDMS. After a little bit of searching, it was just an option to change in the device settings. By default, the Nexus 5 USB computer connection is in MTP mode (Media Device).
What you have to do is:
Unplug the device from the computer
Go to Settings -> Storage.
In the ActionBar, click the option menu and choose "USB computer connection".
Then select Media device(MTP) or Camera(PTP) based on your requirement...
Plug the device and you should have a popup on the device allowing you to accept the computer's incoming connection..
I hope this will help!

Resolved. nexus 5 PC Connectivity
hackdisk said:
Not sure how many would read such a long post for a question, but here goes...
Any help is appreciated!!
1. Problem
In short, I plugged in my Nexus 5 to my laptop in MTP mode, it does not show up in "My Computer".
I just wanted to transfer files to my phone via USB, not even using ADB yet.
I have yet to solve the problem after googling around for a bit.
Relevant XDA threads that I remember reading are this, this, this, this and this.
I have tried numerous combinations of (un)plugging my phone / (un)installing drivers / rebooting my laptop and phone / switching usb ports / turning USB debugging on and off / connect in PTP mode / ...
As a workaround, I am now transferring files using the AirDroid app, which is really convenient with acceptable speed.
Still, it would be nice to know why the problem occurred and see if others have similar problem.
Below I will describe the devices I have on hand and more details on the failures I have encountered will follow.
2. My Devices
A. an old Galaxy Note
B. the new Nexus 5 with the stock micro USB cord
C. new laptop
- 64-bit Windows 8 Pro (not upgraded to 8.1 yet)
- only USB 3.0 ports
D. old laptop
- 32-bit Windows XP Home
- only USB 2.0 ports
3. Details
Scenario A. Nexus 5 not showing up in "My Computer"
Naturally, the first thing I tried is to simply plug my Nexus 5 in to my new laptop. I was used to Android devices working just like that!
However, my Nexus 5 does not show up in "My Computer" after a loooong wait.
On a closer look, my Nexus 5 (only) appears in the "Device Manager" under "Portable Devices" as "MTP USB Device".
It shows my device to be "working properly". However, I cannot uninstall/disable it when my phone is plugged in (normal?)
Frustrated, I decided to unplug my phone. I have the option to "Unplug Nexus 5" under "Safely Remove Hardware", but the operation always times out, so I simply unplugged it.
Then I tried with my Note using the same cable. It works flawlessly either in MTP mode or Mass Storage mode.
Scenario B. Nexus 5 shows up, but is really sloooooooooooooow
At some point, I turned on USB debugging.
With USB debugging on, my phone appears under "Portable Devices" as "Nexus 5" (and in some other places according to what drivers I have installed).
I was quite pleased for a few seconds as my Nexus 5 now shows up in "My Computer"!
However, it took a few minutes to list the folders I have under my phone's internal storage.
Attempting to copy a 12MB file to it gives an estimated time of over 2 hours.
Scenario C. Success?
After tinkering with it for some time to no avail, I was beginning to worry if I have gotten a defective hardware.
Then I remembered I had an old laptop stashed somewhere, so I tried connecting my Nexus 5 to that.
And... voila! It works without a hitch (MTP mode, USB debugging off).
A maybe useful note is that I have used both the old and new laptops to transfer files to my Note before.
4. Possible causes
While many seems to have solved the issue by simply unplugging and letting Windows reinstall the drivers, I have no such luck.
I sincerely hope that it is not due to any hardware defects since
a) my Note can talk to my new laptop through the same micro USB with no problems, and
b) my Nexus 5 can talk to my old laptop.
I feel that this is a driver-related issue but I am not sure.
Is it possible that there are compatibility issues with using USB 3.0 port (which should be backward compatible...) or a 64-bit Win 8 Pro?
Any help is appreciated!

Hello !!!
I faced the same problem with mine...
Couldn't connect my phone with my laptop.
It installs the driver but not displaying the folder in my computer.
I uninstalled the Existing samsung driver in control panel.
Then the issue has been solved,
Or uninstall previous mobile's drivers
Try this!?!

Search for Universal Driver here in XDA. Had the same problem most of you are having. First try and BAM! Works like a champ...
NEXUS 5

Problem solved for me
I have no more issues what-so-ever after I unninstalled ADB & SKD drivers...Windows(8) installed my phone by itself after a restart and it works as it should in MTP mode and PTP mode.

[Q] Nexus/Android with Win 8 is a pathetic story

Hello
:crying:
I got my N5 today, and like my wife's N7 and my N10, NONE of them will show up on windows explorer (windows 8.1)
I can unlock, root, install custom recovery, all good, but as far as actually SEEING my device on the computer so I can drag and drop stuff, well, I literally have been spending almost a day trying to sort that out and have not got any closer at all. It is really pathetic.
I've changed the windows Unsigned drivers thing (though the drivers must be ok if I can do all that other rooting etc)
But yet when I uninstall the drivers to try installing them again, win8 says "Android ADB Interface. The third party INF does not contain digital signature information"
But I'm pretty sure that when I reinstall them AGAIN, I will still nto be able to see any of my Nexus devices on Windows explorer... despite them showing up in the Windows Notification under USB, and they are mounted there... I can UNmount them!
Something is way off kilter here, its with 3/3 devices, perhaps win8.1 is completly Android unfriendly, or?
Advice/help MUCH appreciated for someone who is going nuts here.

Did you turn MTP off to install the drivers to make sure ADB is working correctly? If so, did you check it to turn it back on? I am having no issues with Windows 8.1.

Same in Windows 7, I can't see my mates N5 on my Windows 7 machine but it's fine on his (he got the generic drivers from Windows update whereas I had mine from the Google SDK so that might be something to do with it?...)

It's just hit-or-miss. It's not Windows 8.
My work computer got a fresh image about 2 months ago. I've plugged other Android devices in, but haven't plugged in a Nexus device (or one that utilizes MTP the same way). I plugged in the N5 when I got it, and it worked flawlessly. My gaming PC at home has the Android SDK installed and it worked perfectly there. My HTPC does not have the Android SDK installed and nothing shows up in My Computer at all.
It's a weird android thing.

There has to be a physical reason for it (unless we are to consider the metaphysical - past lives, re-incarnation of gadgets, Steve Jobs curses and stuff...) and it does amaze me that it still seems so hit and miss. When I first got onto android a few years back, you just plugged your phone into USB, ANY ONE ON ANY COMPUTER and whammo, you'd get both Ext SD adn Int SD mounted... reliably. I'm sure that was causing security and stability issues so all manufacturers seem to have snuffed that out.
so that MTP toggle is at settings > Storage > settings in storage
but it makes no difference still not vis in WinExplorer
Cheers

Settings/Storage then hit the advanced menu button on the top right to enter "USB computer connection" and make sure MTP is checked.

I had this problem extensively, when trying to Root my Nexus, I went through uninstalling and re-installing drivers repeatedly, it was obnoxious, but i did end up getting it to work, so don't necessarily give up. I am running Win 8.1 though, eventually i had to go through Wug's Root Kit, and into the advanced driver installation settings, and install the raw drivers. (By booting windows into disabling secure driver certs.) Once i did that it gave me significantly more access, also try toggling your camera one on, the PTM or something, and switching back and forth with MTP.

I must say, I did leave that part out of my replies. I too installed the raw drivers using Wugs toolkit. Maybe that is the x-factor.

Enable USB debugging in developer options.

Nexus Root Toolkit includes a variety of USB drivers you can try, as well as a few utilities to help you diagnose and fix android driver problems. That's where I would start. You don't need to use it to root or anything (unless you want to) but the driver utilities in the toolkit have fixed a number of problems I've had with android drivers over the years. I currently have my nexus 5 / 7 / galaxy working fine on two computers with windows 8.1

Not really the same at all but I had a hard time getting my S3 to be recognized on my computer at work running XP.
In the end the problem was the generic USB drivers that were installed had to be manually removed; even the official Samsung drivers wouldn't overwrite them. After a bit of digging and prodding I got it to work.
My Nexus was recognized without issue on my Win 8 machine.

You'll have to try a variety of different drivers to get it to show up properly. My N4 and Note 3 had no issues showing up, but the N5 wouldn't. I had to uninstall all the old drivers and started with brand new Google drivers to get the N5 to show up. Now it's there.

This happens to me every single time with a new device so I know exactly what to do now. It's not a driver issue, it's a problem with windows 8 and how it searches for drivers.
If you have the Android SDK installed properly just open up device manager > right click on android device > Update driver software > browse my computer > Let me pick from a list of device drivers on my computer > select the google adb driver from here.

Another problem I had was remembering to accept the ADB on my phones end, I never had to do that with my HTC one, so when going through rooting the raw drivers were likely unnecessary, I just hadn't noticed the primly on my phone when the first drivers I installed worked.

Hello guys, thanks for the various responses...

Yeah, i have tried that and it says I have the best drivers already installed. Oddly I can use Nexus Root Toolkit fine, so there has to be something right about the drivers... just not the part that shows up on a computer.
I'm convinced there HAS to be some scientific way of doing this, its such a common problem, it would be great to really figure it out. The problem is, one has to try 100 things before it works, so it becomes almost impossible to know which actions to attribute as the solution!

Hello guys
Following Wugfresh's instructions to the T...
I tried drivers Option 1, (Universal) and the result was exactly as with the Raw (Option 4) drivers... So I uninstalled the drivers, ran ran USBDeview and uninstalled 7 devices like "Google Nexus ADB Interface" and "USB Composite device" and "Nexus 10".
Then tried Option 2.
The installation did not go exactly according to Wugfresh visual guide, so I cant be certain, but I do know that installingPDANET drivers only work if you select MTP, otherwise it will not find the tablet/phone.
After the instalation, the app called PDANET installed on computer, not on my tablet. My PC showed a pop up notification when tablet USB debugging is turned on, but again, it was not visible in windows explorer.
I then was going to try Option 4 again, and Uninstalled drivers in device manager WHILE I STILL HAD THE TABLET STILL PLUGGED IN, so I am guessing though PDANET uninstalled, the drivers remained (which I think is what Wugfresh's process would have done if it had run according to plan. I ran USBDeview and uninstalled the same 7 devices.
Then
Plugged tablet back in to attempt Raw drivers, but all of a sudden, the device was recognised and for the first time visible fully in Internet Explorer!
So basically it seemed to be the PDANET drivers that worked, though I have no idea if that would have worked had I tried these drivers in the first place.
I hope that helps someone!

OP, are you running W8.1 64 bits or 32 bits ??
I had my Sony Viao running W8 64 bits & hated it, downgraded to W7 64 bits and it's very happy getting along with Nexus 7 - going to play with N5 later on. Good old Dell Latitude is running W7 32 bits and it's my main machine to unlock, root & flash and so far so good - yet, I was reading about someone running Vista and had issues with the usb drivers.
I have 2 fully licensed W8 safely tucked away and the way it's looking, I might never get out of W7 - let alone then upgrading to 8.1 for free - getting reminders from $S a few things already.
Most of the time, the mess are caused by conflicting drivers installed & loaded - I keep a clean & lean desktop to do these bench work, and even though it is a PITA, starting clean with minimal programs (and apps) installed is often a good start - turn off antivirus & firewall, especially if connectivity is not needed - enabled access only if it is required and/or necessary.

I've also noticed that on my Nexus 4 I can only access adb in PTP mode, doesn't work at all with MTP enabled.

64 on the two PC's in the same room, HTPC's and laptop are 32 I think, but I have not tried them. I did a fresh Win 8.1 install on Tuesday and had no drivers from any devices other than the ones I manually installed with Wug.

Yeah, well try the PDANET (worked for me, though was my last resort as I don't like to install stuff that is a/ meant for something else, b/has some software I dont need that comes with it... but I did manage to keep the drivers and UNinstall PDANET software by keeping the tablet plugged in when I uninstalled PDANET... try it.

Nexus 5 Is not seen on PC!

For some reason, my N5 can't be seen on my PC. It doesn't show up in device manager, and the phone itself doesn't prompt me for any kind of connection (mtp for example). I think its a driver issue, does anyone know a way to help?

Same thing with me. But I screwed something up.. I was having trouble with the drivers so I used the first guide on theandroidsoul that was posted in the stickied how to unlock the bootloader thread. After I uninstalled the driver in device manager on my win7 computer like it says in step 3 of the guide my computer no longer detects my nexus5 or nexus4. They both charge but they aren't listen in device manager/no connection sound when I plug them in.
I have restarted my computer a few times. Made sure usb debugging was on in the developer options.Toggled MTP on and off. I also checked on another computer that it wasn't the usb cable.

Same here! anyway to get those old drivers back?

Okay now this is weird. Anyone reading this must think I'm and idiot. I know for sure it wasn't working before. I used 3 different usb cables on both n4 and 5. I wiggled them and held them in place leaning in different directions just in-case the usb male end wasn't making the connection. I just tried the n4 one more time and it worked, then tried the n5 and that worked too.

went to device manager when i had my nexus 5 hooked up and it show nexus 5 with a exclamation mark so i uninstall.but usb debug has to be on.
now disconnect phone and turn usb debugging off .
after u do that connect phone and click on storage and click on 3 dots on corner and select mtp and drivers shoud install and it should work.
its all i did. keep trying.after uninstalling drivers reboot pc too.

I tried this a couple of times! PTP but MTP isnt...

If anyone was playing around with NRT or other similar tool kits & had universal USB drivers installed to unlock, install custom recoveries & root, that could've "wrecked" other drivers & settings on it (Windows 7 ??) - one way to restore the connectivity to the N5 is to use MS's System Restore, go back to the earlier date - it should be successful restoration after it finished & reboot. Strange & hard to explain, but it worked & it was too late at night for me while helping out to work the logics behind it. The laptop normally see the N5 upon usb cable plugging in & open with the prompt to read the folders & files.
No matter what, usb debugging off & on, it was no good - only recognize the N5 when switched to Camera (PTP) mode & can only see 2 folders, normally - MTP or Media Device is the default setting & all the "SD" folders visible ...
Once reconnecting via usb cable, let it sit for 1 or 2 minutes so that the drivers can "wake" up and install & recognize the device(s).
Grrrrr, upon further checking with my old faithful HTC, the desktop OS seemed to have "corrupted" the USB drivers and now it is only reading it as a Removable Drive & not as HTC device.
I would go back & follow Littlegreenalien's steps to see what happen and then attempt a System Restore, time to brew up some coffee this weekend & deal with this minor challenge. Wondering if it's the new KitKat thing - and, sidenote, both N7 (2012) and N5 are generating random bug reports even on rooted stock rom & kernel. :cyclops:

Didn't think of a system restore! Man that's a good idea, I'll try it when I get home. My N5 also generated a bug report around when I was trying to fix this problem!

Let us know how it turned out, look at Window's Control Panel, do you see Portable Devices & under it, it should say Nexus 5, and click it to see the drivers (total of *.dll's and *.sys on my W7 Ultimate 32-bits OS)
Now that everything has been restored, "Auto Play" popped up after a pause of few seconds with usb making connections. Rebooted the laptop & now it's seeing the HTC again after auto reinstall drivers.
Just in case anyone, off-topic slightly, if anyone is playing with their Nexus 7 sideloading KitKat & small OTA patch, you should also see Android Device under the Control Panel & the Google Nexus 7 ADB Interface - with USB Debug enabled. But, with the Nexus 5 connected, it is showing "Google Nexus 4 ADB Interface" while showing it as N5 under Portable Devices ... what the heck !
I'm going to leave it alone for the time being, if it ain't broke & is working, leave it alone & let it be. Call me lazy, TGIF - not going to go thru the routines of uninstalling drivers, rebooting & all that and ruin the webcam, camera & other usb drivers loaded on the laptop. I can run ADB and Fastboot commands, etc. just fine now.

I hope this will help!
