so it works _without_ applying patch-btusb-suspend. That would be  
great news and mean that there is no bug inside the USB and/or  
Bluetooth subsystem. It means we just have a  bug when handling the  
multiple interfaces. And that makes actually sense.

Dave, I will prepare a minimal patch set for you today or tomorrow.
