Very nice. I am currently looking for some info to solve a problem with
thinkpads and logitech cordless mice over ps/2. Basicly the wheel doesnt
work. Looking closer they dont respond to the imps/2 or mousemanps/2
protocol. Since cordless mice are more common than thinkpads, I think the
problem would be solved if it was with the mouse. So I am guessing the IBM

Where do I find the public available protocols, and the secrets? :)
