I just installed my new control panel for the x3, and so far its pretty sweet.. Everything seems to be working corectly.. except that i am not sure how to use the usb ports.. I pluggd my 120gig external hdd. into it hoping it would be reconized but it was not. I have many cpu games, roms, and xbox games copied to the hdd and i was wondering if there was a way i could load a game of the hdd through the dashboard, and how i might set it up..?
