just a few extra infos since I've got the same problem:
When I recieved my new Gyro Mouse I just plugged it in the running system, wich caused, that the three buttons could not be used, BUT when I hit the F6 or F8 on the keyboard, I could control the absolute volume or media position...
After a reboot, the three buttons on the mouse are working, but there is no way to scroll absolutely neither with holding down the buttons or the F6 or F8 key on my keyboard...
Don't know if this helps, but I'm also looking forward to someone helping us out...
