Tried this. Got a popup during the install asking me to insert my adapter. Never resolved after inserting the adapter. Rebooted the computer with the adapter already inserted, and still didn't recognize it. I'm wondering if the USB drivers on my backtrack install aren't borked. Seriously, though, this makes too much sense to work. I'll keep you posted if there is any resolution.
on a side note, is there a command to list all usb devices connected?
Update: Figured out what I was looking for. lsusb
lsusb shows the device, and lsusb -vvv looks fine compared to some similar logs i've run across online. That being said, it's still not creating an interface.
Did figure out that my processor is x64 though, so I'm going to try reinstalling bt.
