Basicly you set sample rate to 20 followed by 40 and then 60 at last 
(these numbers are decimal!) and then read seven bytes from the data 
port that are the PnP ID. There's one quirk though with some very old MS 
mice that send 'P' followed by a make/break sequences (don't remember 
the exact numbers of these codes) instead of the correct PnP ID. The ID 
that comes back from mouse is in format PNPxxxx or MSHxxxx.

The code for sending PS/2 commands and receiving the results is already 
present in the current psaux driver (function SendCommand I think).

Hope this helps,
Filip
