Windows recognized it and installed drivers (flashes green when first plugged in) but then doesn't light up at all after that. Is it supposed to light up, how can I verify correct drivers are installed or make sure its working. Under the DVDKey tab, should USB be checked? its greyed out I have to use the probe to flash the DG 16d2s now right? BTW - I am trying to flash my Liteon ver 0251, will I be able to use my same ol device?
