Hi
Ok, here are the descriptions:
	Panic 0x22:
An irrecoverable USB (hardware) error has been detected.

	Fault 0x1f:
Either the chip received an unrecognised SDD/SDP (upper interface) 
command message from the host or the chip ran out of pool memory when 
processing the message. In either case, the message has been discarded. 
Presuming the fault was issued because of an invalid SDD/SDP message, 
the firmware has survived the problem.


Unfortunately panic code 0x01 ain't the normal value, that's 0. And 
when everything is working all right hciconfig won't even show any 
"panic" value at all. It only display non-zero values.

	Panic 0x01:
The useless catchall. Used to indicate an error where no other 
appropriate panic code exists.

I'm only guessing but chances are the internal USB transfer might cause 
the errors too. You might want to try with a Knoppix or other live CD 
first but then I think you should make your machine to dual boot 
between Linux/Windows.

To my knowledge you must get the unique firmware from each respective 
dongle manufacturer, but I'm a bit uncertain of this.
