Hi all!

I have a microsoft notebook presenter mouse 8000
(http://www.microsoft.com/hardware/Presenter/productdetails.aspx?pid=085) and I have managed to have it working (as a mouse). When switching to presenter mode, the multimedia keys work (volume up and down), but the forward and backword keys do not. I tried to get the key codes with xev, but nothing shows up. Even the scan code (with showkey -s or with getscancode - http://keytouch.sourceforge.net/) nothing shows up.

However, with hcidump I can see that something goes through:

I do not know how to interpret this information. Does anyone knows if
the problem is related to the bluetooth part or to X?
Is there any possibility of getting it working?

Cheers,
