Need help connecting bluetooth keyboard

Hi Folks,

I'd like to connect a "Microsoft Wedge Mobile Keyboard" to a notebook (Lenovio n581) with fedora 18 (kde).
Output of the command "hcitool info":

With Microsoft windows 7 it works fine on the same computer.
The connection process doesn't complete. It seems to hang before asking PIN.

Can any body help?

Kind Regards,
Michael
