Solve : USB Keyboard/Trackball Combo?

1.	Solve : USB Keyboard/Trackball Combo?
Answer» Using WINDOWSXP SP3 then TRIED SP2. When I power on the PC, the USB keyboard works but not the built-in trackball. It appears to be using the bios driver. To get the proper driver to work I have to UNPLUG the USB connector and PLUG it back in. Then the APPROPRIATE driver is used and it starts working. Any suggestions?
