As long as the micro usb pc pretest works there is no way that the Demon is malfunctioning other than visual damage etc..? Last night I had my demon installed nice and tidy all continuity test checked out but I kept getting unrecognized device in windows and it would boot console but not demon. Turned out I had a short on the QSB so I went a head a removed the Demon and gave it a pretest and it checked out good.
