Hi,

I have a Dell XPS 8700 win 8.1 and was trying to install a usb 3.0 video grabber device (Blackmagic Intensity Shuttle). It turned out the new windows 8 usb driver stack doesn't support this, so I tried to force install the old Windows 7 Intel usb 3.0 driver (disabling driver signing and hacking the .inf files), but alas! the computer now gets no usb input meaning I have no means of controlling it. I'm stuck at the wallpaper before logon. Any ideas how I can get back in and revert the driver?

Thanks in advance,
Lasse

in the device manager click on view at the top and in the dropdown
show hidden devices
then uninstall all listed usb items
turn the computer off
unplug usb plugs
reboot twice
replug in the usb plugs

if this gets you back to normal in win8

go into the properties of Blackmagic Intensity Shuttle)

and try running in win7 compatability mode
