Good.

No. You are only ensured that you (the host) will not reacive any other
data before the client is ready. And it signals this with AA 00, if the
client is a mouse. There is ofcause some mice that don't stick to the
specifications and sends the AA 00 at once. Thats another reason why I
suggested a disable stream first.

While you at imps2 couldn't you rewrite it all to automaticly find the
best imps2 mode the mouse knows? 5 button wheel is missing (which I have
just bought:) Here is a link about imps2 and how to detect the features of
present imps2 mice:

If you don't I will (in the future).
