It's what it came installed with, and I havn't had a reason to change it. It's mostly a game and internet box. Though now that I can run Linux easily I'll be doing most of my interent browsing from there.
The manual for the switch box does have some information on mice, but basicly it amounts to saying if it's not a generic or a MS mouse your hosed.
My copy of Kylix came to today, but I won't have time to install it till this weekend. Once I get that running, I'll probably spend more time under Linux then Windows.
