use a bluetooth headset with an unsupported bluetooth adapter

ive got a sound in problem w/ my pismo, so im looking to other methods of talking into my computer for skype. And ive got an hp bt300 that works great on my pismo under 10.4.8. (i kno its for a printer but it works great on os x!) i was wondering if there was any way to get it to see a bluetooth headset? are there any hacks? Thanks!
