Changing to an illuminated trackball

Rather than USB, I would just tap off one of the spare molex connectors from the PC's power supply. You can buy a molex extender cable and then cut off the end. The Red wire is +5v, the Yellow is +12v, and the Black is the Ground. Since you're going to use the Lightmite, you don’t need to worry about any resistors, and I think it can use 5v or 12v. I would go with 5v - just hook up the Red and Black wires.
