I installed Ubuntu 10.10 on my MacbookPro6,1 and the Magic mouse worked OOTB.

but now that I'm trying to get scrolling (and more?) to work with the Magic Mouse, but I noticed that my machine isn't recognizing a bluetooth device.

When I start Bluetooth Preferences, it tells me that there are no bluetooth adapters present. My bluetooth magic mouse is definitely working.

Any ideas on why the bluetooth device wasn't shown and how I get it to show up? It works even when the 'bluetooth' service is stopped.
Code:
$ xinput list
