So please let me know if you can think of a possible solution...
BTW: It's a Toshiba A9 notebook which has a usb bluetooth and a usb
fingerprint reader - the usb bluetooth needs to be enabled and shows up
in lsusb afterwards (wifi and bt share the antenna AFAIK so wifi is
enabled per default and bt is disabled) and the fingerprint reader is
disabled via autosuspend. None of them show up in lsusb, so they
shouldn't keep usb active I guess.
