[Q] device not recognized over USB

I've been trying to connect my Trasformer to my computer over USB for a while now so that I can use Nachoroot. When I plug it in, a bubble pops up on my PC on the bottom right saying "USB device not recognized". If i go into the device manager and click update driver and have it look in the folder with the USB drivers from Asus's website, it says that i already have the most up to date drivers. I've tried uninstalling the device, installing the package with Sync and web storage, but get the same result.
I have tried using a different cable, a different computer, and a different operating system (specifically windows 7, windows 8, and ubuntu). I've also restored my Transformer using the option in Settings.
Anybody have any ideas as to what will work?

Have you install Asus PC sync?
If you haven't you should

yes, i've installed sync.

Take a look at this thread, especially the "trouble shooting" portion
http://forum.xda-developers.com/showthread.php?p=13635629

I had looked at that thread before and have tried all of those steps, and tried them again, but no luck.
One note being that with the other drivers from the hotfile download on that thread, i'm unable to install them. In the device manager on my computer, when I plug the computer in it shows up as an unrecognized device, and when I try to use those drivers it says that they don't apply.

I am having the same problem. I was rooted on the 3.2.1 system with a US version BAO transformer TF101-A1 and the computer was able to use the drivers. However, I could not upgrade and was having issues unrooting, so I did a factory reset then upgraded OTA 3 different times until I got to the ICS 4.0.3 (which runs fine, just unrooted!). Now I cannot get the transformer drivers to install! I get the "USB Device Not Recognized" error and in the device manager it shows up as an Unknown Device under Universal Serial Bus Controllers. I try to update the drivers using Asus drivers, Vipormod drivers, and the drivers I used to originally root it which was Brks_rootkit_v7, but it won't accept them. This is without Asus Sync installed and trying on four different computers using Windows 7 64 bit and two different cables. I even tried loading the Asus Sync and it will not find the device. When I try to boot into stock recovery, I just get an Android that falls over with a red exclamation point. Also to note, my wife has a transformer still on 3.2.1 and rooted and it recognizes it immediately on all four computers using either cable. I have been everywhere searching for an answer (including this site) and tried just about everything. I just submitted a service claim email to Asus telling them that after the update I am unable to use Asus Sync and the drivers aren't recognized. I am extremely frustrated! Any help will be appreciated.

These also seem to be a similiar problem and as yet a solution has not been found.

Thank you for your quick reply. I will head over there.

Just to clarify, I can download the appropriate file, flash that file (using cwm) and then it will boot up in ICS or do I need to update to ICS after that?
Thanks,

If you have kies then just install kies on pc then connect your phone;dont need to install driver manually.

I had the same problem long ago
You need to remove all the Samsung drivers and kies if present in your PC and install Samsung USB drivers (find them from xda or Google or install kies)
Connect your phone in download mode and let the system detect your phone

This is a NEW problem that is affecting many thousands of people and it happened after the last update.
I have a GT 19300 v4.1.2 and all was well until I installed the update.
Now when I connect the phone to my PC (W7) the system sees it and tries to install drivers but then gives a message saying the it failed to install them.
Device manager now shows my phone as an unknown device and it didn't before.
I have tried lots of fixes and there are now dozens and dozens of them on different forums and none of them work.
This is not a cable problem and not a Kies problem. Lots of people including me have installed and uninstalled it.
I have the Samsung GS3 Int ToolKit an it installed the latest drivers today 1.5.15.0 and they didn't help.
Many people have tried a reset and all it did was waste their time so don't bother.
It looks like only Samsung or Google can fix the problem but I'd love to here of another fix.

Today I disconnected the internet and plugged the phone into a different USB socket before booting the PC
The message I got this time was,
Samsung_Android X Device unplugged
Unidentified Device X No driver found
The above makes no sense to me but if it does to you then please let me know.
Thanks,
Michael

I got a message on my cellphone "the software does not exist on your phone to allow it to connect with your phone. You need .. XP with Windows media player ..." I don't remember the exact words". I'm using W7
Then when I unplugged my phone W7 said drivers are being installed and then said successfully installed. I plugged the phone in and it was recognized.
I opened Samsung GS3 Int ToolKit but it didn't show a serial at the top. I attempted to do a back up of all programs but gave up after a message, "waiting for ADB mode" appeared on the screen for over an hour. My phone isn't rooted; is that why?
The phone is no longer being recognize

[Q] End of my USB tether

I recently rooted and unlocked my bootloader on my N5 and now cannot for the life of me get MTP installed on my W7 PC. Ive tried using Wugs to clear drivers and reboot and reinstall but all it does is install ADB Interface driver.
Ive also changed USB port, used my N5 USB cable, and also cleaned drivers but nothing. In occasion when looking in USB Deview it shows an MTP driver but it just wont do a thing. Ive unticked MTP and switched to camera and back. Nothing.
So, I tried my N7 and surprise, the same thing has happened. Ive installed SDK and tried updating drivers, still nothing. Ive been at it for about 7 hours all in and about to throw the phone at the wall.
Can anyone offer an advice. ive read posts and tried the suggestions there but nought. I vaguely recall a programme that will wipe any naughty bits of rogue drivers (once uninstalled) but cant remember the name of it.
In portable devices I have E/ drive.

No one out there who can help??

[Q] MTP not working.

Hi! I need help with an issue on my device, it's a Moto G XT1032 running the optimized version of Kitkat 4.4.4 provided by user lost101 and previously available here: http://forum.xda-developers.com/moto-g/development/rom-stock-motorola-lollipop-rom-t3017510 .
My laptop is running Windows 7, 64 bits.
The problem I'm having is that whenever I connect it to my laptop the device starts charging the battery (hence the cable works) but doesn't allow me to use MTP. The USB icon doesn't prompt on the status bar and on the laptop nothing pops up.
I've turned off and on again the MTP check box on setings/storage. Already uninstalled and reinstalled the Motorola Device Manager (at least three times). Also tried installing the Drivers by themselves and is still not working. Found a thread (http://forum.xda-developers.com/showthread.php?t=1115366) where multiple users claim to have find the method as a solution but doesn' work for me.
Any solution you can provide? Thanks in advance.

OnePlus One not recognized in My Computer

I tried to access my phone's internal storage but the phone doesn't show in My Computer. The Portable Device in Device manager says MTP USB device and it has the yellow triangle on it. The Samsung driver is the Android Composite ADB Interface with no triangle. I have debugging on but the MTP device driver always fails whether debugging is on or not. I used Koush's drivers found here on XDA but same old thing. The Portable Device used to show up as A0001 and /or One but now it doesn't and I don't understand how that happened. Can someone enlighten me and perhaps solve this problem? It's been very frustrating as I just spent 13 hours trying to get my phone working (Thanks Heisenberg for fixing) and now another 6 trying to figure this out. Please HELP if you can. Thanks!

Even I had faced this problem on Windows 8. I had installed drivers 4-5 odd times. But later I just flashed CM11S zip via recovery and enabled USB Debugging Mode and it finally got recognized on my laptop.
I was facing many issues with all lollipop ROMs. Hence I reverted back and now everything is working fine.

I, too am using CM11s as Lollipop has too many bugs for me at this time. Maybe I'll try re-flashing CM and see what happens. Thanks for the reply

My question is: How can one flash from recovery when the file that needs to be flashed cannot be sent to the phone because it's not recognized by the computer?

Nevermind...I figured it out and flashed 11S successfully! Everything shows up now on computer. WOOT!
