This actually made it, thanks so far! (usbmodules is located in
/usr/sbin/ on my machine)

Of course, the main problem still exists. Additionally, the USB audio
module is not loaded any more (for the built-in microphone of this

Sorry if I ask something stupid, I am a total USB rookie - what's that
/usr/sbin/usbmodules file for?
