Interesting. Does not me help here.

I have to unload uhci_hcd to enable C3 (the bus master activity is only
caused by this module here).

Nothing else, even ehci_hcd can stay active (which puts me into the
interesting position that I can use an USB2 drive, but not an USB1 mouse
if I want C3, for example. ts.. ;))
