THANK YOU!!! I've been waiting for someone else to have the same problem!!! I'm relieved it's not just mine. I'm assuming you did a manual install also? Is yours rooted? One person suggested ClockworkMod but I'm a little nervous about rooting. I've been doing the manual installs but that's as for as I wanna go. I can't stand the idea of bricking my phone.

My phone is new out of the box!
I found that on two Windows XP machines USB storage doesn't work. I then plugged it into a Win7 box and it worked perfectly. I also used a different cable with the Win7. Try a different cable and try Win7.

I have Windows XP on my work PC and Windows 7 Premium 64 on my home notebook and the USB worked fine on 2.3.3. Every since I did the manual install of 2.3.4 the USB functionality is gone. I'm thinking maybe the ROM is used wasn't incomplete. It's beginning to look like the only way to fix this is to root my phone

FWIW I did the manual update (full rom) and USB storage works fine on my Windows 7 Ultimate x64 box.

Yeah, I'm thinking maybe the one I installed wasn't the full ROM. As soon as I see people saying it works great I go ahead and use it. Do you know of any possible fixes without rooting?

No first hand experience, but would it be possible to download the full rom and manually flash it again?

Trying to figure that out. I've been told try ClockworkMod and go back to 2.3 but I'm trying to do it without rooting.

Try a different USB port
If the update was incomplete, the update would have failed the signature check. The first time I connected my Nexus S after manually patching to 2.3.4, Windows 7 Professional X64 did not detect it when connected. I unplugged it and used a different USB port and it worked. I then tried the original port and it also worked. I would try a different USB port and a scan in Device Manager before changing the ROM.

I also have Windows 7 Prof. 64 bit, but switching to different ports didn't work. It won't install the drivers. What else could that mean if it isn't the ROM?

I had this problem immediately after flashing CWM.
I booted into the ROM, then, while the USB was plugged in, powered off the device, and turned it back on. It then seems to work everytime I turn on the device, as long as I don't boot into recovery.

Me too

I had a the same problem with my SGS.
The trick for me did: disable usb-legacy-support in your motherboard-bios.

Have you tried re-installing USB driver from the latest android SDK?

Kind of strange, it was working great yesterday and today couldn't connect. Right clicked on android_winusb.inf and selected install and it started working again. Not sure what could have changed from one day to the next. But at least I know what to do when it happens again.

Never tried that. Doesn't that involve rooting or unlocking the bootloader? Both of those wipe the USB storage.

Don't have a custom ROM. All I did was manual bootload 2.3.4 on stock Android. The weird thing is when it's plugged in(charging only) and I turn it off, it starts to power down and then freeze. The screen doesn't go black until I pull it out. Then when I plug it back in it automatically powers back on. Basically, I can't seem to plug it in while it's powered off.

I have no idea why but my suddenly works again. Im happy but confused

You shouldn't need any drivers at all for windows XP vista 7 ect. Mounting your SD card, using flash drives... all use the same USB mass storage divice driver built into windows.

Yes, I just tried this. It still doesn't seem to work. It keeps saying my drivers are up to date but it's still not connecting to my USB storage.

[Q] Cannot connect to PC - Cyanogenmod 11

Trying to use odin to flash the stock rom but I cannot connect to pc. I have the correct drivers and usb cable and have tried 2 different pc's that have worked in the past. Running cyanogenmod 11. Any help is appreciated.
Thanks

Perhaps bad cable, or try different usb port.

Does it recognize the phone at all when it's connected? Does the phone recognize it's being charged? Are you on Windows 7?

ran into the same problem. any thoughts?

Do the ##3284# Menu an see if MTP and ADB is checked.
If that doesn't work find a USB Storage app from the play store and that forces it in that mode. If that still doesn't work then you need to gather up all your Micro USB cords and try every one. Or use the one that came in the box

I had that same problem before, I fixed it by uninstalling drivers and installing again. Maybe flash another rom and see if that works. I know if you have usb fast charging enabled enabled on ktkernel that will prevent your computer from recognizing phone. Good luck

Adb is not working because debug usb doesn't works.
A month ago i have a bootloop (security error on boot) flashing the bumped recovery TWRP, i solved installing jelly bean stock firmware and then stock kitkat via kdz because download mode worked even I used kdz , but I can't remember if I have used the usb connection after that I think so.
Already tried reinstalling drivers and nothing changed.

Bricked my 6p and computer wont recognise it

Ok, so i managed to brick my nexus 6p, it will not boot into android, stupid as i am i do not have a backup on the phone, and on top of that, windows does not recognise my device in bootloader mode. Of course i have tried installing USB drivers, but strangely my computer will not even recognise that im plugging in a USB device, i/e it wont even make the USB connected sound.
Not really sure what to do, but im hoping anyone could maybe help me out, thanks!

I tried to install franco kernel on my chroma rom, and it just wouldn't boot.
Also, I am using the drivers installed by the unified android toolkit.

Do you still have the Chroma zip on your phone? I'm guessing not, but if you do just flash that. You could try uninstalling the drivers that you currently have and installing the drivers from the Android SDK. I have a link to the SDK download page and instructions on how to install it in my guide. Otherwise, do you have access to a Linux machine? No drivers required for Linux, you just need to install the Android SDK and adb and fastboot should work out of the box so to speak. Or if you don't have access to a Linux machine you could even create a bootable Linux usb and do it that way.

Oneplus 2 no OS installed

Hey guys,
Earlier today I wiped my phone while trying to update the system, but when I tried to install the update it failed. That means that I'm now sitting without an OS on my phone, only able to access TWRP Recovery and Fastboot. I've successfully installed adb drivers and all of that, but when connecting the phone to a computer ADB doesn't find any devices and device manager only sees it as an unknown USB device (Device Descriptor Request Failed). I have been seaching for a couple of hours now and have not been able to find anything that works, so I'm hoping that you guys can help.

When I try to update the driver, as it says in step A-7, the only unknown device is the unknown usb device and when I try to update that one with the qc folder, it just says that Windows have determined that it is up to date?

Have you tried connecting to PC while in TWRP recovery ? You should be able to access internal storage using mtp. Then you can copy another rom & flash it.

I have tried connecting to Windows 8.1 on a Macbook Pro while in TWRP Recovery, and that's where it said it was an unknown USB device.

Any other ideas, because I do not own any other USB type C cables. The one I'm using is the one that came with the phone, but I have never had any issues with it.

Lets try installing the drivers again. If this doesn't work, then it should be a cable issue OR usb port issue. Try this on another pc.
1. Download Oneplus2 USB drivers -> https://www.androidfilehost.com/?fid=24052804347833370
2. Before installing the drivers, Disable Driver Signature Enforcement. -> https://www.youtube.com/watch?v=NM1MN8QZhnk
3. Install the drivers & Restart.
4. Now try either connecting to pc while in TWRP or fastboot.

you can flash factory image through fastboot

Maybe this is a bit annoying but the best solution is to buy another cable since a few weeks ago I had the same problem, bought a new cable and the problem was solved. Hope this helps
Then flash the OS through TWRP using the advanced tool that allows you to sideload files using adb.

How to enter mtp on recovery/fastboot?

I've done the same thing in the past (erase everything) , the solution that worked for me is this:
1.Always have a twrp back up on a usb stick.
2.Buy a cheap usb 2 type c to usb adaptor.
3.Enter twrp and restore the back up.
This way you do not need a pc/drivers etc.
I hope it helps.
