Hey guys i recently got a new pc with windows 8.1 and it doesnt recognize my gnex. whenever i connect it (i tried various combinations of mtp,ptp and usb debugging on and off) it says usb device has malfunctioned. same thing happens in bootloader mode. if i go to device manager i cannot see it under either portable devices or adb interface (the option is not present) i just see a yellow exclamation mark under "usb controllers> unknown usb device(port reset failed)". I have also tried all usb ports both usb 2.0 and 3.0.
anyone have the same problem? the phone works perfectly with the same cable in my other laptop with win7
I solved the issue. It seems that my USB cable was the problem. I changed it and it installed fine. I didn't think of it at first as the same cable works perfectly fine with win 7.

I always have the problem that I can connect to my phone, but sometimes when I try to open a folder, it keeps loading and won't open the folder. Don't think that's an USB problem too, but I'll try...

After rooting the phone (in this case to leedroid) I have been having trouble with 2 xp machines at work.
Both detect the phone as "unknown device".
Doesnt matter what I select, charge only, sync, disk drive, adb usb debugging.
I have uninstalled / reinstalled htc drivers repeatedly.
Tried just using android sdk drivers.
I have deleted
C:\WINDOWS\system32\drivers\Wdf01000.sys,
2. Remove: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Wdf
3. Remove: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Wdf01000
I have also removed anything under Vid_0000&Pid_0000
Everytime I plug it in, windows detects it as unknown device. It wont let me update the drivers.
Help please!
what do you mean it prevents you from manually updating drivers? has it ever worked before? have you tried showing hidden devices via command line then removing the old device manually and then reconnecting it?
yep did all that hidden devices stuff too.
You wont believe this but I saw a post about someone using a thicker usb cable. I recently switched to using a retractable micro usb cable at work. I brought the original htc usb cable into work today, plugged it in xp detected the phone straight away!!!!!
who would have thought a cable was the problem!!?? All that wasted time!
htc one x not connect to pc with usb cable (pc windows 7 32 bit) (developer options, usb debugging tryed) There is no message and no one else's cell phone screen and pc. different usb cable and tried and different pc, but the same result. android 4.2.2 sense 5.0
please help..
On phone after connecting nothing appears too?

Try reinstalling the usb drivers or use a different cable. Make sure you reboot after driver installation. Also, connect the phone with pc and go to device manager and see if it appears there. if it has a yellow triangle in the device manager then you need to update the driver.
Edit: when you connect your phone, does it start charging? because if that is not the case then your phone`s usb port might be damaged

also try another usb port, sometimes one usb port at my pc makes problems.
have you tried another PC?
Maybe is there anything corrupt whith your USB connector..
I had this issue and assumed it was the PC. One day I used the HTC cable that came with the phone and it worked fine. Turned out to be the cheap USB cables I got on ebay. Phone would charge fine, but would not connect properly.
What is needed to connect the Tab Pro 12.2 to Windows 7 via USB? When I attempt to connect Windows doesn't recognize that a device is plugged in at all. I can't find a setting anywhere on the tablet to enable USB connection.
Things to know:
I've installed Kies 3 on the computer but it doesn't recognize the tablet being plugged in either.
I've installed the Samsung USB driver.
I've successfully connected the Tab Pro when in download mode since I was able to root it.
USB debugging is turned on (also tried it with debugging turned off).
Android 4.4.2, build number KOT49H.T900UEUAND4 (rooted)
What am I missing?
Unplug the tablet from your pc. In Kies 3, under Tools, reinstall usb drivers. Reboot pc. Connect the tablet to usb. See if that gets it working.

Thanks for the suggestion. Still no joy. It's like there's no MTP driver or something. When I plug it in to the USB port the tablet recognizes it as it "dings" and tries to charge (it can't because the USB port doesn't supply enough current). However, the pc never makes a sound and doesn't recognize any thing's been plugged in.
Is there some setting I'm missing on the tablet?

I doubt it's the tablet. Probably a driver issue with windows. Try a different cable (usb 2.0 or 3.0) and usb port on the pc

I have had this issue with my Galaxy TabPro 8.4 (similar device). Why don't you try reinstalling the software and drivers on your computer. Also, have you tried a different USB port? These simple techniques have solved the problem. Seems like a problem with your drivers.
Restart your device as well. A simple restart can clear issues.
im having the exact same issues, reinstalled windows, now i cant get my tab to connect ... tried different ports I finally got it to show up as an MTP device but computer doesnt like that one bit.
worked for me (Samsung tab pro)
had the same problem, all i did was shut down my tablet and start it back up (not restart option but actually shut down one) then it popped back up on my laptop as connected.
i think it has to do with the batt. not being able to charge on the laptop and it just over looks it........braking it down Barney style .
Hi, my phone stopped being able to get a USB data connection. The port is physically intact and does not wiggle. I've tried two different Macs and one PC, different USB-A to -C cables (all verified by Benson Leung). Also toggled USB debug, MTP and PTP modes from Developer Options, rebooted phone and computer. When I plug the phone in, it only goes to Charging mode. Android File Transfer doesn't see it and 'adb devices' comes back empty. There is no notification offering me to select connection type. Did I miss anything or is it time to send it in? Thanks, Tony
What OS are you running on your Windows - checking your Device Manager under Control Panels - are all the Google / N5X drivers installed and working correctly before this ? Try uninstalling, reboot PC and re-install them - and, use different USB port to connect the cable (what kind of connections are you using ??)
Can you run ADB ?
Thanks I'm primarily using a Mac (10.10.5) but the PC was running Vista. It was a borrowed PC so I didn't install the drivers. I don't think it's a driver issue though since nothing shows up in device manager and the phone doesn't offer to switch out of charge-only mode. Also the same Mac worked previously.
Hey so i have been having a big problem recently. my htc one m8 32 gb verizon version doesnt get recognized by my computer. ive tried different computers, ports, and cables. i even got a new charging port and installed it but nothing. when i plug my phone into my pc, nothing pops up. the phone only charges but no option to transfer files. htc sync says no phone connected. Also have usb debugging enabled but nothing. running on 6.0 marshmallow and any help would be nice. Thanks!
If you look at your notifications, there will be one you can't clear saying USB Charging this device. Click on the notification and change it to File Transfer.
Couple comments:
1) Try the genuine HTC cable that came with the phone. I've noticed that some 3rd party cables will only charge, and not connect by USB/MTP. I assume the pin layout on those particular cables is not exactly the same as what HTC uses.
I know you probably already tried this (HTC cable) but this may at least narrow down the variables.
2) Assuming a Windows PC, go to device manager, find the phone (hopefully, its listed) then select the option to manually select a driver. Then pick the generic driver for "Android MTP device" (or something like that, forget the exact name). If often have to do this to get my home PC to "see" my M8 by USB. Although my work laptop doesn't have this issue. Your results will vary depending on your exact PC configuration, it can be very confusing and frustrating!
m8 problem
First sorry for bad English.
My M8 is not recognized by my computer. I've tried extra ports, cables, drivers .. Windows 7 64 bit is computer, android 6 is on the phone. Only the phone detects it is connected to a computer and offers the options, mtp, ptp, charging ...
What can I do?

I don't see what the problem is. The PC recognizes the phone. Are you trying to access a function such as fastboot or adb, that is not working? You never say in your post what the problem is.
