Have you read the following forum thread:
http://ubuntuforums.org/archive/index.php/t-378000.html

Apparently Windows altered the hardware device Id of my bluetooth module. I
have a Wireless 350 Bluetooth module from Dell in my Dell Latitude D620. The
default deviceId is 413c:8103. But till yesterday it was set to 413c:8105 in
Ubuntu??? Some say this is caused by Windows Vista, but unlike others I
never had Windows Vista installed on my laptop, only XP in the beginning.

After reading that thread, I created a partition for windows xp, ran the
firmware upgrade utility for the Wireless 350 Bluetooth module from Dell *
(DFU.exe), rebooted into Linux and now my deviceId is back the default:

`lsusb`:
Bus 005 Device 005: ID 413c:8103 Dell Computer Corp. Wireless 350 Bluetooth

I was struggling for quite a while on this problem, but the easiest way to
solve this problem is to install windows again (if you haven't allready) and
perform the firmware upgrade. I know it's not the best solution, but hey,
now I can actualy use my bluetooth module under ubuntu.
