I have a laptop sporting one of these USB based chips "built-in". An
HP Pavilion zd8004AP

Same, although, when I first purchased the laptop, it came with
Windows XP installed, and the bluetooth _WAS_ working. After
repartitioning the 80Gb HDD and re-installing XP on a smaller
partition, using the discs that came with the laptop, I couldn't get
bluetooth installed again. I kept getting errors saying that the
bluetooth license was not valid, and asking to locate the correct
license file.

Under linux, it works fine, although I have to specify the interface
(hci0) every time I use things like hcitool and hciconfig. For
example:

~ $ hciconfig
hci0: Type: USB
BD Address: 00:00:00:00:00:00 ACL MTU: 377:10 SCO MTU: 16:0

This is kind of an interesting idea. I would have assumed that the
BD_ADDR was a harware adress, and not alterable by software.
Certainly, what I assume was/is the original adress is stamped on a
sticker on the module (I pulled the laptop appart to check it out last
week).

I'm planning on looking into it some more once I have some more time
