I've had a separate powered usb hub in my cabinet for years to handle the inputs from the control panel. Recently, I decided to purchase a usb expander that plugs into the header on the mobo and fits in one of the rear slots.
After I installed the unit and connected everything back up, I found that the trackball wouldn't work. All buttong, joys and the spinner worked as they did before but no trackball.
Anyone have an idea as to why?
The usb unit I installed is powered via 5V.
