I'm having trouble connecting my phone to my PC to transfer files. The phone never seems to register on windows, there are no "device inserted" sound at all and the phone is not listed in the device manager. On the phone, it is not even showing the little notification to change USB mode from Charging to File Transfert. Even in the settings directly, the option does nothing. Latest Google USB drivers are installed.
When the phone is in the bootloader, it shows up in the windows device manager with "Unknown usb device (device descriptor failed)".
I've tried multiple PC and cables, rebooting in safe mode, same thing!
I'm running TWRP recovery with stock ROM and ElementalX kernel, might that be an issue ? Thanks

Let me start by saying I have read dozens of threads on connection issues from the original galaxy to the s2 and none of them have worked. Here is my problem. When I plug in my phone I get a MTP connected dialogue box but kies will not recognize my phone and odin won't recognize my phone in download mode. My computer's device manager doesn't even show drivers installed or any yellow triangles at all. As a matter of a fact, my computer does NOTHING when I plug in my phone. No installing drivers dialogue box or anything. I have tried manually mounting usb storage mode to no avail. I can not transfer files, root my phone or do anything. I'm running stock EK02. Also, with usb debugging box checked my phone just charges with no pc connection at all. with usb debugging unchecked it will show the mtp connected but my computer doesn't show anything
Here is what I've tried:
Installing and reinstalling kies about a dozen times.
uninstalling and reinstalling samsund drivers
rebooting my phone
tried different computers
I EVEN BOUGHT A NEW COMPUTER (brand new nothing installed)
Then I bought a new usb cord
restarted my computer several times
checked then unchecked usb debugging just in case
Please Help, I'm completely stumped......
I can get on multiple chats for anyone interested (gtalk, facebook, irc, whatever) or take responses here. thank you in advance.
--------------------------
UPDATE: so it was the USB cord the while time. Apparently you should really only use the USB cord that came with the phone, which I lost and had to borrow from someone else.
I've been eager to try Scott Crosler's new CM11 but didn't have time until tonight. To ensure cleanliness, at the bootloader I erased cache, system and userdata. I've flashed ROMs dozens of times, and as usual, there were no problems with fastboot recognizing the device.
I then entered CWM, and it was the darndest thing: three fast USB connection beeps and this error:
"Windows could not install driver software for your device."
But I've had the generic USB drivers installed for two years! At first I thought it was interference from the Samsung drivers when reflashing my wife's tablet, but I tried our two laptops, same result. No matter that I right-clicked "Nexus 7" in Device Manager and pointed it to freshly downloaded drivers, even that I tried installing drivers using the SDK Manager,
"Windows could not install driver software for your device."
I've read that turning off USB debugging helps, but um, with an erased /system, I had nothing to boot into!
Normally I prefer flashing via ADB sideload. To get up and running again, I flashed TWRP and used its feature of mounting USB-OTG and flashing from an external drive. Once I got into CM11, I turned on and off USB debugging, but I still can't install the USB drivers, and ADB can't recognize any devices. At least there's flashing via external flash drives.
Has anyone had the like?
didn't see win 8.1 mentioned but thought this may help? http://forum.xda-developers.com/nexus-7-2013/general/windows-8-1-users-careful-t2856908. I have had problems with drivers in past. adb composite are the ones that work for me. I simply removed drivers under android devices in device manager then plugged in device. GL.
Windows 7 here, but thanks for the suggestion anyway.
This morning I can connect it as a media device, and it's in Device Manager just fine as "Nexus 7." But turning that off, it becomes "flo" in Device Manager and can't find the updated drivers. And either way, I still can't get it recognized while in recovery mode. Ah well, as I said, at least TWRP has the option to mount USB OTB and flash files from an external drive.
Let me add that I already tried another cable (for our Samsung tablet), and tonight I see that I can connect it in MTP mode. In MTP mode, it shows up just fine in Device Manager (under Portable Devices), but turning off MTP throws it under Other Devices with the dreaded ! (and I just can't get it to install the driver no matter where I point it to). And no matter what combination I try, I still can't get ADB to recognize it at all.
Although this is for Windows 8.1 it may apply to your situation: http://forum.xda-developers.com/nexus-7-2013/general/windows-8-1-users-careful-t2856908
As I e-mailed you, sfetaz's suggestion of USBDeview is part of the solution! I still can't get it recognized in booted Android as anything but a media device, but now it's fine during recovery. Darndest thing I ever saw in 19 years of dealing with Windows drivers.

Then in an old bookmark, I tried Koush's universal ADB drivers.
http://download.clockworkmod.com/test/UniversalAdbDriverSetup.msi
Even if USBDeview hadn't helped, it was still good to clear out all the old devices I no longer use. Definitely a handy utility to keep around and recommend.
I can not get my device to show up in almost every mode via usb. The ONLY thing that works, is, from recovery, choosing apply update from adb. Then, I can see the device as sideload with adb devices, but every command results in "error: closed"
When just in recover, download mode, or powered on, the device will not be recognized. I have tried Windows and Linux mint on my computer, as well as another mac computer, all with 3 different high quality cables that work fine for other devices.
In windows, device manager shows the error "Device descriptor request failed". This all started out of nowhere the other day.. I had it connected via mtp, it disconnected and reconnected itself a few times, then quit working all together.
I've tried HTC sync manager, as well as standalone drivers, but I doubt it is any computer issue since i have tried multiple OSs annd computers....
Any ideas? I'm trying to backup some files and finally get this thing running something other than stock.
I have a problem.
My screen is broken. Now I want to send him to OnePlus.
But before that I want unroot it. Or at least reset to factory defaults. But both things fails.
I have the latest FreedomOS Rom. Since then I can no longer use TWRP. When I start my phone to the recovery the screen goes black and nothing happens anymore.
The same happens when I put it back to factory settings through the settings menu .
I've read there is a modified version of TWRP.
From here begins the real problem. Windows doesn't recognizes my phone.
In Device Manager it appear as "unknown USB device (failed request for device descriptor)"
What I've tried:
Boot in to Bootloader
Original (Dash) USB cable
Other USB cable
WIndows 10
Windows 7
USB debugging on
USB debugging off
OEM unlocking on
OEM unlocking off
USB configuration: File transfer
USB configuration: MTP
USB Configuration: Charge
Anyone have an idea?
Maybe it's the ROM. But I cannot flash another ROM because I can not get into TWRP.
Maybe it's an option to flash the modified TWRP without a computer. So right from the bootloader. But I do not know if this is possible. And how it should be done
I'm having the exact same problem. Did you find a solution?
In windows 10 -> i get Device Descriptor Request Failed
In windows 7 -> Unknown Usb Device (Installed Correctly)
whenever i try to update device driver with ANY driver (oneplus... or generic sdk driver) I get a message saying "doesn't contain a suitable driver for your device.....)
I went to device manager > right click mtp (unknown device) > update driver software > browse my computer > let me pick > mtp USB device > happy me
Windows it's the problem. I reinstalled drivers, adb, nothing. At work i try it & it works. I reinstalled windows. Now works.
I'm on windows 10 x64.
Damn it, I don't think windows is my problem.. i tried Windows 10 / Windows 7(2 diff computers)
i can't even see the phone as MTP..
Found any solution to this? Having a similar issue

Here's some different things you can try:
1. Make sure USB Debugging is enabled, and make sure you get a pop-up on the g3 asking if your PC has permission to connect to your device
2. Try a different port on the PC or try a different USB cabl
3. Try a different PC
Hi, thanks
Already tried but nothing, it seems the usb chipset deleted its info, I don't know if there is any way to flash it
