I was not such lucky with mx900.
My experience:
bthidcontrol works ok:

When I start bthidd it waits for mouse connection forever, clicking on mous=
e connect button does not seems to have any effect,
moreover hcidump does not show any traffic.
But bthidd listens on /17 and /19 (why not /11 ?)

On mouse I have picture where attaching procedure shown as
1. Click connect on mouse
2. Click connect on USB receiver.
Looks like mouse gets passive state and waits for receiver connection after=
connect button.
Mouse works Ok under winXP with onboard bt.
(Is there way with hcidump "listen" traffic between XP and mouse to get clu=
e ?)
If mouse already connected with USB receiver it do not answer even on l2pin=
g.
