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

anyone figure out how to get usb mount for the s3 for Verizon. Im looking to purchase one within a day or 2 and just wanted to make sure if i hook my phone up to the comp. will it let me copy files over like things used to be?? Don't want to have to set up some type of server and do it that way just want to plug and go.... thanks for any feedback it will make my purchase that much easier......
it comes built in... its not called USB mount, its either MTP or PTP. I haven't really figured out the difference between the two yet, both seem to work just fine for browsing the files on the phone and ext card.
so plug and add files from my comp is a go then... good to hear,,,,

If you have windows plug and go as windows supports mtp natively. If you have a Mac computer there is a file from Google you download and install that gives the macs mtp access.

I find the PTP setting (i.e., appears and works like a USB thumbdrive) more convenient than MTP, which has a specific interface that not all Windows applications are able to handle in my experience. I use MTP for "synch" programs, such as MediaMonkey, which act like a more open and usable form of iTunes for our Android phones.

Someone else posted something similar to this in another thread and I got a bunch of flak for answering that Mtp works the same as mass storage mode. Apparently people running Linux cannot use this option, and it is different than mass storage or usb mode and I don't know why. Still have yet to get an answer in the other thread "how to enable mass storage mode". Maybe I can get one here?

Linux has been shown to have different results depending on using MTP or PTP. Windows doesn't seem to care except sometimes it gets picky and doesn't recognize the "hardware ID" of one version but does of the other.
If connected to a PC via USB and your phone is set to MTP, it's seriously as easy as drag and drop.
I've seen many solutions for the reverse, but not for this problem.
I've got my Nexus 5 connected to my PC right now. I'm trying to copy files off of it, but the Nexus doesn't realize it's connected to the PC. With Android debugging on, Windows realizes there's an "Unknown USB Device" connected, but Android doesn't recognize the computer is connected at all. I've tried the other computer in our house and had the same issue.
I'm running on 4.4.2, so it shouldn't be something too out there, but I can't figure out what else to do.
On the other PC, did you use a different cable?

Using a different cable I was able to get the Tethering options to show up. Activating Tethering, the Nexus 5 was recognized as a "USB Composite Device". Trying to manually specify the USB driver to use hasn't changed anything.
With the different cable, deactivate tethering then delete the device in device manager. See if anything else shows up. Could be cable issue, could be phone port issue

Got it working. At some point I unchecked both the MTP and PTP connection options, but for whatever reason plugging the phone back into the computer didn't make the notification pop up. I had to go to Settings -> Storage -> (menu) USB computer connection in order to turn it back on.
Sorry for the trouble.
So this is very strange. When i use to plug my G2 into my mac and use Android File Transfer everything worked fine. Recently, I went to transfer some files over and I plugged my G2 into my macbook and it automatically chose the "PC Software" option and says "Installing PC Programs, check your computer." I go to select Media Sync (MTP) and it just automatically goes back to the PC software option. When i click Android file transfer it just tells me to plug in my USB. I have my drivers installed for my Mac and i've even tried it on my virtual terminal and the same thing keeps coming up. It's so annoying bc it use to work just fine.
Someone please help me
Have you tried a different USB cable?

Ya and same thing keeps happening. I am using the cable that came with the G2 when I got it. The same cable that I used when I use to be able to send stuff back and forth between android file transfer. It's very very strange
Hi,
I'm sure this is a simple one but I can't solve the problem!
I have a laptop at home with windows XP which, although it will see the phone as a hardware device, will not let me transfer data to/from it. When I select PTP it works fine but nothing happens with MTP. It works fine on the work laptop...
I've tried uninstalling the drivers, re-connecting phone so the drivers are automatically loaded again to no avail. Tried switching on USB debugging too (this seem to kick start the PTP option though). It may have happened when I was loading lollipop on my phone using my laptop, but I can't be sure. I put the SDK(?) folder on my desktop which I have now deleted, although this idea my be a red herring.
I'm sure this is easy, any ideas?
Cheers.
Check there's not an acer device shown as connected as a recent windows update screwed up the drivers

Thank for the reply.
No its not showing Acer, its actually showing "Google Nexus ADB device"?!
With usb debugging both on and off?
Sent from my Nexus 5 using Tapatalk
Tried both and neither make a difference!
It'll be a driver issue, when it happens it's a pain in the ass. When you figure out the fix. You're like 'damn that was simple' always the way! Lol. Have you checked the driver issues thread?

I'm sure you're right! No I haven't I'll go have a look.
