If you are running a Shuttle motherboard, you might need to install a board-specific driver. Although from your rig profile, it doesn't look like this is the case. If you remove it, will Windows auto-detect it again at startup? Have you installed the 4in1 drivers for your KT? Maybe flashing the BIOS? Is there any device missing from your system that you notice should be there? If it's not hurting anything, I'd suggest just leaving it there...
