PC doesn't recognize Nexus 5

Hi everyone,
My Nexus 5 isn't getting recognized by any computer. I've tried plugging it into both Win 7 and Win 8.1 machine using different cables (stock N5 and stock N4 cables), it doesn't show up as a media device in Computer anymore. You can see that in device manager, it shows up as Unknown USB Device (Device Descriptor Request Failed). I'm unable to update the driver to the original Google USB Driver; even if I do it manually, it says the latest drivers have already been installed. I've also tried to uninstall and remove the device from device manager, restarting both phone and computer, nothing worked. Any kind of input is appreciated.
Edit: I've also tried connecting as both MTP and PTP modes.

I had the same problem and did same as you. I has something to do with USB-divers on the computer. So I did a dirty trick: I installed Sony PC Companion and rebooted (I know, seems strange) and now my Nexus 5 shows up on the desktop.

Thanks for the suggestion. I tried it and it still showed up as Unknown USB Device (even after I uninstalled it from device manager).

[Q] this device cannot start (code 10)

I was moving some pictures from my phone to my computer today, and windows explorer stopped working when it was almost done.
I started windows explorer again and selected the memory of my phone and it was loading really long (longer then the first time).
So I plugged the phone out of the computer (without ejecting it) and now my computer doesn't recognize my phone anymore .
(the computer does recognize the phone, and it will charge so the cable works, but it fails to install a driver for my device)
I already tried this:
Rebooting my phone and computer.
Using another USB port.
Checking if my settings on the phone where correct.
Plugging the phone into my brothers computer and that worked (so the problem is with my computer, not my phone).
Uninstalling the drivers of my phone by going to my Device Manager. (I uninstalled MTP USB-device, under Portable Devices)
I tried to update my drivers (MTP USB-device) and I clicked browse my computer, let me pick, ok.
Could someone please help me?

The correct drivers are installed? Tried with different USB cables? Tried all USB ports on the computer?

yes to all :/

The phone used to work with the same computer and USB cable?

If ur rooted install multirom and install cm13 as secondary os.. then connect to ur pc while ur in cm13 it will detect the driver after that unstall cm 13 and connect as u do normally
like if worked

hey i found away around it thx though!

How did you fix the problem?

"hey i found away around it thx though!"
But why in the name of all that's holy would you ask the question and then not share the answer for others who regularly have the same problem? Keeping info to yourself is the best way of maintaining your "zero thanks" status...

oh sorry for not sharing what i did to solve the problem! here is what i did!
1. connect phone to pc
2. unlock
3. swipe down and touch the notification that says "usb for charging touch for more options"
4. select the option you want
easy

USB Connection Issues

I just rooted my s8+ with partcyborg's samfail and everything is working great except the usb isn't being recognized. I can see my phone on my computer and I can move files to my desktop but on my phone I get this message - "The connected device is unable to access data on this device. Reconnect the USB cable and try again." I have USB debugging enabled in settings. I'm using windows 10. ADB is up to date. I installed the samsung USB drivers. The device isn't recognized in kies or smart switch.
I'm at a total loss here. Any ideas? Could this be related to the 80% battery bug I was seeing? It's been at 80% for a while now.
Apologies if this is an obvious fix. I haven't rooted a phone since kitkat I looked around but the other threads weren't helpful.

So what do you wanna do with your USB connection? Just MTP (e.g. transfer files like you would when connecting a USB-Stick to PC) or you wanna do some ADB operations?
If you just want to transfer files, there's no need to have USB-Debugging enabled (in fact this is kind of a security risk when you connect to an unknown pc)

I'm trying to use the phone as a bootable drive because my USB stick was stolen. I want to put a linux distro on my laptop.

Yeah I've been trying to use drivedroid but it says there are issues with the mass storage. I'm going to send the dev a message with the ROM and see if there's anything he can do. For now just gonna flash back to stock

I'm sure he has looked into it. I talk to him quite a bit now that I think about it I have not heard nothing about it
