USB Ethernet adapter was working but then stopped (Windoze 8)

When I initially plugged in the adapter, and installed the driver, the device worked perfectly well for about an hour. It the stopped working, and no matter what I do, it will no longer work - It just says there is a problem with the driver.

I tried restoring the system to an earlier point, before the device was installed, and re-installed the drivers, to no avail.

I have the zip file output from the debug tool, but cannot see how to attach it here.

Any help greatly appreciated.

PS: I did try disabling McAffee
