      and you didnt find any solution?

      my problem started after i accidentally switched the + - connections in my carpc power supplier,
      the 25amp fuse built inside the supllier melt so i fixed the connections and replaced the fuse, the computer started normaly, the screen looks good, normal mouse is working, keyboard is working,GPS is working,
      but like in your case when i connect the screen usb cable into the computer i dont see any msg\warning or any sign, and its not working.

      still looking for an answer

        You probably fried the USB Controller. You can get new controllers only for about $50.

        Just need to be more careful with your connections...
