you can get it working in xp, its just really nasty to do unless there is a quick workaround, figured this out today and it's now working fine
way i did it and kind of discovered by accident was to start over fresh and install win 98SE (other os's compatible with kiky-joy probably work also) then install the kiky joy drivers, plug it in and let it install, then install windows xp over it as an upgrade, it will then work in xp...or at least it does for me
stupid i know but it worked, annoys me though because when you see soyo say the adapters chipset can't support xp then you manage to get it working like this, it makes you see that they are just too lazy to do drivers for xp
