Hi,
I've had a Gtab for awhile, since just after last Thanksgiving, and I can adb to it fine.
I just received a new Gtab that I purchased on the woot deal last week, and that seems to be working fine, EXCEPT I can't adb to/with it, from my Windows (7) machine. I can adb to/with the original Gtab fine with this same Windows machine, but when I plug the new (woot) Gtab into the same USB port, with USB Debugging enabled:
1) It shows up under Device Manager as "Portable Devices", H:, instead of as "adb composite...." device, and
2) "adb devices" lists no devices, and I cannot "adb shell" to it.
3) In dmesg, I am seeing the following message when I plug in the USB to the new Gtab:
"init: sys_prop: permission denied uid:2000 name:adb.connected"
I don't know if the above message is related, but it seems like it might be?
I can transfer files via USB to the new Gtab, and NVFLash appears to work ok with it, but I just can't connect via adb.
I've been trying to diagnose the problem on the IRC, but haven't gotten a resolution, so I was hoping that someone here might have some idea(s) how to diagnose and fix this problem?
Thanks,
Jim
ADB Issues
Do you have USB Debugging turned on? Also, have you rooted your device?

Yes to the 1st, and for the 2nd, I tried it both without and with (temp) root via z4root.
Here's a followup: I have another Windows XP machine that's setup with adb and the adb USB driver. On that XP machine adb works with both the old gtab and with the new woot gtab, and I can switch back and forth from adb and drive mode (USB debugging enabled/disabled, respectively), with both the old and the new (woot) gtab.
Strange!!!

It's obviously something in Win7 but darn if I know why. It's almost like something is hardcoded to work on only that specific device. Very bizarre!
roebeet,
Yes, I don't know either, but I'm thinking maybe it's some difference in the "order" that Win7 decides which USB driver to use vs. XP. On the IRC, I had mentioned that I was originally thinking of trying to disable the Harmony ("portable device") device, to see if it'd then "pick up" the adb composite device, but then I tried on the XP machine, which worked, so that was "good enough" for what I needed to do.
The new (woot) gtab should be turned over to my son tomorrow, so I probably won't have much time to mess with it after that, but maybe this thread will serve as at least a note to others who run into this problem.
badfrog said on the IRC that he knew of someone else who had a new woot gtab that worked with adb, but that person only had that one gtab, whereas I had my original gtab plus the new woot gtab, so maybe it won't be a problem for anyone who has only a single gtab.
Later, and thanks,
Jim
I had a hard time getting adb setup on a Win7 (starter edition) netbook. First, try deleting the device manager entry for the gtab and let Win7 redo it, you'll need to unplug and replug the gtab. There was also a utility I used to remove entries called 'usbview' or something. I don't have the netbook at hand and this is from memory.
Read this guide.

You gotta edit the inf file, remove all previous android devices from your system, etc..etc.. it's a bit of a task but should take you less than 10 minutes.
I have a Nexus S, and had a Nook Color, had to do these steps and my gTablet now works with ADB. My Nexus S probably doesn't now because of the changes.

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
Sent from my HTC Glacier using Tapatalk
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 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,

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?

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

My question is, what would you do in my situation?
My Xoom connected to my computer (HP Pavilion dv6000) (Windows Vista) once before in past times. It will not connect anymore, I have done everything possible that people have said to do. Still in the same situation.
I connected it to my mothers Toshiba Satellite U505-S2950 (Windows 7)after installing Moto software, and its working perfectly.
Should I re-install Windows/Re-set to default? I've tried everything, from installing drivers, to changing permissions, to installing adb, blah blah blah.
I just recently found DropBox which I am using now, until I can figure out exactly what to do with my HP.
Anyone? TBH: I don't want to use my moms laptop every time I want to transfer a movie to my Xoom, rather it be mine.
Appreciation is high.

So I guess you are using your original Xoom USB cable, and have tried different USB ports (like the ones on the back if you have a tower), you tried with debugging on and off, you've tried with the USB plugged into the Xoom 1st and then into the computer as well as the other way around...do you have Windows Media Player (9?) installed on your pc? It seems it needs it to connect....
Its not a solution to USB woes as I reckon I am in the same position with XP Windows machines, but an alternative.
Why not run a FTP Server on either your Laptop or your Xoom....
I doubt its as fast as USB transfer but may be quicker than Dropbox (definitely quicker for me in the UK with cruddy upload speeds !!!)
I use FTPServ on the PC and SwiFTP on the Xoom as the FTP Server - I just switch each one on when needed depending on which copy method I feel like using
I use Total Commander for the FTP Client on the Xoom.

Interesting idea...
This I suppose could be seen to be quite drastic, but it will fix 99.9% of all USB related issues across windows OS's
*** Read first before actioning ***
>Right click My computer and manage, you are using Vista? So will probably need to run as admin.
>Go to device management and expand Universal Serial Bus controllers.
>Ok delete the lot
>Yup delete the lot
What this means is that it should now prompt you to reinstall the drivers for any USB device plugged in to the PC, yes you may find that you have to unplug and replug in your keyboard and mouse to re-install the drivers for those devices. But it should also re-install the Motorola Xoom drivers also.
At the end of the days its quicker to try this than re-install Windows
Unfortunately not every USB Root Hub or Host controller displays what it actually is, some do but that's a case of right clicking each one to see what it is. If for example it states that its a mouse then perhaps don't delete that one but hopefully you get my drift.

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

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.

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?

Found him a while after posting here; man, did it ever work for me (and like you, I'm running Windows 7 64-bit, so.....).
Hope it works--best of luck, like I said, I'm in knuckles deep already here!

Even manually it cannot get windows to accept these drivers for the device.

Have you tried going into your Windows 'Device Manager' and deleting ALL your old occurances of EVERY Android device there (making sure to check 'uninstall drivers' as well during this process)...then starting with that last link I sent cha, again (the universal ADB link)?
Try this--at some point, I was also forced to do this...maybe more than once.
That will be all I can say to help ya! Good luck!
I've been searching for days for an answer to this and I can't find it. The biggest issue is that every time I plug my TF101 into my computer, I get Windows' wonderful "One of the USB devices attaching to this computer has malfunctioned" message. I get this using the OEM cable and brand new after-market cables. I've found a lot of different forums with similar problems but my symptoms list is different. Here's what's going on:
* The tablet charges just find through all of the cables despite not connecting properly through the computer.
* The dock (keyboard) works without issue and charges properly.
* Flash drives work properly in the USB ports on the dock.
* Android phone (Razr MAXX HD) recognizes that it's plugged into a device, the tablet briefly acknowledges a device (quarter of a second) but then stops reading the phone is plugged in.
* Maybe of note or maybe another issue, it doesn't want to connect to bluetooth devices, either. It recognizes them but refuses to connect.
* Everything is stock.
I've tried a hard reset and deleting every driver associated with the device properly installed and not. I don't have another computer to plug it into so I can't test that. I fear it may be a hardware issue but I don't want to resign to hardware issues but rather definitively know that the issue is a hardware issue.
Any thoughts?
Thanks,

Linux emulated through VirtualBox, see if that detects it.

Tried it through VirtualBox with Ubuntu and another system (mine is Windows 7 Pro, the other system is Windows XP Pro). No dice on any of them.
My thoughts - bad USB cable.
You probably will say - BUT IT STILL CHARGES....
Yeah, mine does that too. But, one of the pins needed for computer connections is shorted. I used my cable 3 weeks ago to ADB, then last week nothing (trying to ADB to do the Ubuntu Touch resolution fix). Got a new OEM cable (and wall wart) from Office Depot, all better.
Virtualbox/ESXi/VMWare etc... I've had problems with all of them even in USB bridging mode. Nothing beats native.
Make sure the right drivers are installed; remove (not deinstall) completely the current ones as they may be corrupted and redownload ASUS Pad PC Suite from Asus' support site for your OS version, I believe it provides more recent Asus drivers (not 100% sure).
Also try the Universal 'naked' drivers for adb, I always have used those and they work flawlessly, and I included them in my peri tool because of this..
Here's where I'm at:
Don't have access to another OEM cable (hopefully fixing that in the next couple of days) so I can't test that. I did, however, install Ubuntu onto my system natively, plugged it in, and got zero response from the system using every cable that I have. I will buy that drivers may cause erratic behavior and such but not having the system recognize that a device was even plugged in makes me doubt the driver issue.
Thank you all for responses. I'll get another OEM cable and cross my fingers that solves the problem.
Just FYI, I know it's not convenient because it takes a month to get it, but I bought this cable and it works fine for data and charge. No need for an overpriced Asus branded one.

I've run into this problem with another device on my PC. Turned out to be a double whammy: the USB port on the PC acted up; and the driver for that device was partly corrupt. Tried it on another USB port to find out. It's not always the cable.

3 ports later I decided it wasn't a port issue (but I do appreciate the sentiment; I've been there with devices in the past).

I'm gunna try it; the worst that happens is I have another charging cable when I (inevitably) lose the three that I have now :fingers-crossed:

I had the exact problem lol, I thought my cable went bad, I order another and threw that old cable away... damn what a bum, all it was was just the driver? Not sure, but when it does find the drivers and tried to install it, after installing the drivers knocked my wireless Ethernet off and disable too.
Still no dice
One, thanks everyone who has tried to help this out. I'm not tossing out "Thanks" yet because nothing has worked but I am thankful that people have tried.
Two, here's what I've done thus far that hasn't worked.
* Uninstalled and reinstalled (including fully deleting) every driver known to work with this device (including naked drivers). No dice.
* Uninstalled the driver while it was still plugged in and scanned for device changes. No dice (but this got me the closest; it "successfully" installed an "Unknown Device" and had me restart the computer).
* Used peri and hoped it would magically work after it installed the Naked drivers. No dice.
* Went through "[GUIDE] Getting ADB Setup; An Idiots' proof guide on getting ADB working for Rooting!" (no linking for me yet) hoping I missed something when I was installing. No dice.
* Installed Ubuntu and tried from the other operating system. No dice.
* Plugged into a Windows XP computer. No dice.
* Purchased the recommended cable. No dice.
* Prayed that it would work. No dice.
I'm stuck. I thought about sending it to Asus to have them repair it but I've not heard wonderful things about their repair service and I can't be without it for longer than a couple of days. It just frustrates me that Windows knows I've plugged something it but it simply refuses to recognize it, like it's taunting me into staring uselessly into a computer screen for hours without any solution (and hampering the work that actually means something to my life/career/marriage/etc.)
Any other thoughts? The only thing I haven't tried it is installing the drivers to plug it into my fiance's Mac to see if it will magically recognize it. I just wish I knew for sure it was a bad port on the bottom so I knew that I had to send it in to get fixed...
Thanks again!

I'm posting cuz I've literally spent hours and hours searching, trying things, etc, and am stuck. I have several PQs with various CM/LineageOS ROMs. It is not a ROM issue because if I plug via USB into my desktop pc running win 10, they all work as I want. Presumably, it's a driver issue or something related to my specific laptop - I recently bought an old used laptop, originally shipped with win7. After purchase I immediately removed all partitions and installed win10 from disc (fyi, you can d/l win10 iso from microsoft and use win7 oem key to legally install fresh win10, even now the free upgrade stuff is over - that surprised me).
I cannot, no matter what I do, get file access via usb to my phone. I've tried lotsa things. I don't remember if/what I had to do to make my win10 desktop see them - maybe it was automatic, i dont remember, if it wasnt, I easily downloaded/installed what was necessary - but nothing I've tried makes my win10 laptop load the drivers, although it does detect something when I plug it in, and something else when I select MTP on the phone (vs charge). But just exclamation points in device manager and nothing in explorer. Among other things, I've tried MotorolaDeviceManager_2.5.4
It's especially annoying as I have a video on my phone I wanted to send out tonite and can't, spent another couple hours trying. Bluetooth works fine for pictures but freezes at 10% for video, no idea why. But I'd much rather just use a cable than figure out any wireless BS.
Incase it's something specific to this laptop and someone is curious, it's a Sony VPCF115FM. That 'base system device' and "unknown device" are always "!", MTP with "!" only appears when phone plugged in.
Yea definitely a driver issue. When you plug the PQ into your desktop (which seems to work) what shows up in device manager?
Have you tried to right click on the devices with yellow exclamation points and update the driver from Windows update?
I never followed up on this, but still haven't found a solution, and kinda forgot about it. It does work in PTP mode. And works for a newer Moto (Lenovo) phone on this laptop. Yes, I tried the windows 10 device manager update auto search thing (in fact, just tried it again minutes ago before I read this). I'm about to wipe and install fresh as this phone is running crazy slow lately and wanted to copy everything off before I wipe which is what reminded me of this issue - funny thing is that a google search of this problem ("mtp driver motorola photon q windows 10") found this thread as the third search result and I completely forgot I posted it. I vaguely recall I read your reply but was waiting to see if anyone else responded and then just forgot to follow up when it wasn't on my new list...
PROBLEM SOLVED! It happened in TWRP too and sideload was failing (for another reason) but made me try to figure out MTP again.
Found solution here for anyone with similar issue:

Gotta update driver and manually select "MTP USB" from list of devices, in my case I found it under portable devices.
