I have an Logitech iFeel Mouseman USB and i also experience problems on my abit KT7 RAID. The mouse only works within win98 (nonSE) when all drivers are loaded, so when i boot up in safe mode, it won't work. While installing win98 the mouse also won't work, but on a AOpen board with a Duron 700 it does work while installing.
I also couldn't get the iFeel option to work because the setup program just hanged all the time, but after trying 100.000 times, it suddenly worked.
I don't have problems while running win98 "normal" with this mouse, even after leaving the pc on for the whole day. But perhaps you are having some USB port problems?
