[Q] USB Not Recognized

So all of the sudden my computer, or other computers wont recognize my phone.
I might be answering myself, but maybe my socket is kind of/might of broken?
When I connect it, I still get the CHARGE ONLY or DISK DRIVE option, but my computer(s) doesnt recognize it. I have to try several times inserting it for my computer to recognize it. I used my other HTC INSPIRE chargers..same problem..
I read on other forums that, their device is having the same problem as mine, at all of the sudden.
even my USB DEBUGGING mode wont recognize on the computer..
help....
EDIT: some people are saying something about MOUNTING/UNMOUNTING SD CARD.

If you're using windows, check the device manager and make sure it's not an "unknown" device. If it is, try manually installing the device (using HTC sync drivers or Android SDK drivers). If that doesn't work, open the properties of the unknown device, and find the device ID and check it against the listed ID's in the .INF files for the driver. (Had to hack them recently to get ADB working, presented the "wrong" device....)

Win7 Will Not Connect To Xoom

I just got a new Win7 Pc and now when I try to connect my Xoom to it it says Unknown MPT device. I tried installing the drivers to no avail. I didnt have this problem on XP. I am running stock ICS on my WiFi Xoom. Any ideas?

Where did you get these drivers from? Try the ones directly from Motorola.

You could drive removing the current drivers and SW. Try just using the device then runnign the moto install for those drivers. Make sure USB is enabled correctly on the tablet too. Is it charging from the usb connection? You could try a different port it shoudl charge regardless.

Xoom doesn't charge via USB..

I am using the drivers and software directly from Motorola. I have tried it with USB debugging on and off. I have tried switching it from MTP to PTP on the Xoom and still the same results.

Go into device manager and see what's up. Make sure xoom is plugged in beforehand. Right-click My Computer -> Manage -> Device Manager.
If there are no errors (!) to do with the xoom, then some form of driver is installed. Manually delete these by right-clicking on them.
Then take out xoom, and put it back in. Win7 should automatically find the MTP drivers.

I'm getting the same exact problem and I've gone through uninstalling windows media 12 to acquire the mtp drivers and nothing, i can't even get it to install wmp11.grrrrrrrrrrrrr

does the xoom show up in Windows Explorer under "Computer"?

Problems with drivers for MT4GS and win 7

So I have an unrooted standard MT4GS phone and trying to start the rooting procedures, but my computer is not recognizing the phone in anyway other than in disk drive mode. When installed all of the fast boot drivers, standard drivers, HTC sync, rebooted both computer and device, it still is not recognized at all. I have usb debuggin on and i have tried all modes when connected to pc (tethering, disk drive (recognizes it as a removable disk), and charge only). Any ideas what I am doing fundamentally wrong? PS I have searched the forum multiple times for answers but to no avail. Thanks in advance.

I think I have a solution, but I'm not sure. I think you are missing the drivers for it. Google HTC Drivers and it should be the one that's named HTC Drivers 3.0.0.7 or something similiar.

Make sure USB debugging is turned on...

Try going into Control Panel ===>System===>Device Manager ===>USB Controlers & you should see a listing for a Mass Storage Device. If you'll right click on that & reinstall drivers it might get you going. I had to do that myself. It may not want to overwrite the installed ones so you might have to uninstall & REinstall.

You need to install HTC Sync, it will provide the drivers for Windows 7.. after it's installed you can just plug in the device and windows will find and install it. Then you have to close HTC Sync and continue.

Thanks for help.
I tried to uninstall drivers with USBDEVIEW but it's hard to know witch one to uninstall in a 100 drivers list. i removed all called "One" drivers and tried again after reboot comp, with no success
I tried to connect my phone at the usb port who are behind my computer and it works but i still have a message error "unable to find a driver for your device".
So i put my phone on usb caméra mode and it works without driver problem, and i can access the memory storage of my phone
But my phone is still not recognized at the front usb ports of my computer, idk why..

[Solved] USB suddenly stopped working

I have a Nexus 5 that I have had about a month now and I had the USB on it working before about a week ago. I plugged it in today and neither my desktop or laptop could recognize it anymore. Both computers are running Windows 8.1.1 and the issues seems to be new as I can neither get USB storage or ADB to find it. The closest I can get it to working is to switch the USB mode to PTP and it reads that but I don't want to pull photos off. When I have it in MTP, it makes the sound of it plugging in and my phone shows it is plugged into a computer but Explorer shows nothing and it says it is working normally in device manager. I've tried everything from enabling and disabling debugging, restarted both my phone and computer tried reinstalling the drivers (both by the computer automatically finding them and manually installing them) but nothing seems to work. Is it possible that Windows Update could of broke the drivers since my computer installed updates yesterday? I also have Linux on my laptop and it appears to read fine with Linux.

That's the exact issue. If you check in Device Manager you'll see it listed as 'ACER ADB Device' (or something like that). You have right-click on it, select update driver, manually check and go through the list option and choose the MTP driver and it'll work again (and with USB Debugging enabled if you don't usually have it on like me)
I theorise that it's happened cause the Acer driver is digitally signed and the Google ones aren't but I could be wrong. Either way, it's a PITA

OK thanks. I'll give it a try because it was showing up as ACER ADB Device under device manager
EDIT: I updated the drivers and used the USB composit drivers instead and it got MTP working again. When I set it to USB composit, it installed Google's ADB drivers and the Nexus 5's USB drivers so everything is working again. Thanks for your help

I can´t manually update driver because of this:

when i update the acer adb it says the driver is up to date and everything is all same. what to do?

Thanks! Thought I was going to go crazy. Worked for me...

i set the driver to MTP as mentioned above and the phone started to show up on the explorer but now i couldnt copy any files from my laptop to the
phone. It displays like that and if clicked yes then the copy wouldnt happen.what is the problem.

Uninstall driver, plug in device, tell windows to not auto install driver (or disconnect from internet), click to update or install driver, point to folder with drivers, install, all is done.

That msg comes when you're in PTP mode I think...Only certain formats are supported.
Check under storage, expansion menu and make sure you are set to the first option...not PTP.
Above guy mentioned to have phone in USB debugging mode when setting up drivers.

If the device is showing then you need to point to the drivers for it (download them from google). I reinstalled windows a few days ago and had the acer issue (device first shows up in device manager as nexus 5 then switches to acer), windows wants it to be an acer device. Stop windows and then install the correct drivers,
For me I had to click the auto install in windows tray and tell it to stop. After a few times it worked.

No I'm connecting in MTP mode. Ahh its gettn irritating.
