@Tormod: Does your bluetooth device still show up in lsusb when the killswitch is on? If not, it's probably implemented by just disconnecting the USB connection to the bluetooth hardware rather than a killswitch as bluetooth-applet considers them. Unfortunately I don't have any hardware with any accessible killswitch whatsoever here so I don't know what the correct behavior is :/
