Unknown USB Device (Device Descriptor Request Failed)

[careacchiardo]

My computer keeps telling me Unknown USB Device (Device Descriptor Request Failed), so I looked up how to fix it and they told me to uninstall it then scan for hardware changes and it will reappear working properly.:thumb: Only it did not come back working properly, it came back the same. I am also 98% sure that this "unknown USB device" is my built-in webcam that has never once worked:huh:. So if someone wants to help me out and allow me to use my webcam that would be great!

Hi there, can you first tell us what is the Name and Model number of your system?

What OS are you running

im sorry if you already listed this, as I cannot see your specs from the Windows Forum App..

I take it this is a laptop?

 

[careacchiardo]

Yes, this is a laptop. ASUS Notebook Series RALINK/RT5390. Windows 8.1

Webcams are notorious with usb issues when the wrong driver is installed, replaced, or corrupt..

Please download SLIMDRIVERS FREE and scan your devices, update all drivers or at least CHIPSET, USB HOST CONTROLLERS and WEBCAM

Lets start with that...

Btw what USB. Devices do you always have connected to your laptop?

 

[careacchiardo]

I updated all drivers and it worked! But, alas, it is again not working. I don't have any USB devices always connected to my laptop.

This is a handy utility: View any installed/connected USB device on your system

Uninstall things that don't look right then reboot.

how do I know if they are not right?

 

[popeye]

Doesn't hurt to uninstall whatever you don't recognize. Next time you plug it in it will install adain. Great tool for getting rid of old or conflicting garbage.

well, none of this is working. Anyone else got any ideas?

If you suspect your camera is on USB, you can see detailed view of all USB devices and you may recognize it.

It is definitely my webcam, but I still don't know how to fix it. I have uninstalled it and it still does not work.

If you know for certain that its your webcam, then you should go to your laptop manufacturers website and download specifically the webcam driver, and make sure you download the one you have whether its x86 or 64bit and for the windows version you have...
