Logitech TrackMan Wheel Ergonomic Trackball Mouse Model : T-BB18 USB Corded Listed For Parts Or Not Working All the buttons function but there seems to be no power going to the optical trackball and therefore the trackball does not work. Ball Moves Smoothly, Buttons Click As They Should, Scroll Wheel Moves As It Should. Overall very good condition I have listed this as spares and repairs so no returns due to postage costs
