We just need a way to say "I want this to be a hci > device when I plug it in automatically". devd(8) could be used to run hid2hci automatically when device is plugged. devd.conf entry will contain device name, vendor id/device id pair to match againts. after device warm resets itself it will be recognized (hopefully) as bluetooth dongle. thanks, max
