Hello,

 

just bought the nitro vn7 791 and i can't get my webcam to work. found in device manager that i have an usb device with the following description: Unknown USB Device (Device Descriptor Request Failed)

 

Already tried:

 

1. unistalling the unknown usb device, unistalling the usb roots and draining the battery to zero. Then powering it up and asking windows to finding the drivers (when i drained the battery, i used a pin to to push the button that simulate the removal of the battery). did not work

2. installing the acer crystal eye (it says i don't have a web cam)

 

any thoughts?

 

ty in advance.

 

general:

Windows has stopped this device because it has reported problems. (Code 43)

A request for the USB device descriptor failed.
