Correct, libvirtd is the one that detaches the driver when I start the VM.

Please see attached for the USB sniffing on the USB bus with the Crucialtec 
touch pad when Windows starts up and shuts down. To drive the device, Windows 
uses the Crucialtec driver according to its device settings display.

The attached log contains the log information for the mouse (device 001:005) 
and the USB bridge (device 001:002). I cut out the listing for the touch pad 
which is also attached to that bridge.

The strange thing, however, is the following: the mouse works in Windows when 
I do not sniff on the USB bus using usbmon. But as soon as I start sniffing, 
it does not work any more.

Is that log helpful?

Ciao
Stephan
