To start out, is the device being identified as a bluetooth device?
Take a look if btusb is getting loaded:
$ btusb
If it is, make sure that
$ hciconfig
lists it.
If it's listed, try to reset the device using
$ sudo hciconfig hci0 reset
If that works, then it's a kernel bug and your device needs a reset quirk.
