Not sure if this is the right place to post this but my other posts have gone unnoticed so here it is again:

My lilliput touch screen went dead on me. When I plug in the TS usb windows says "unknown device" or "device not recognized by windows". I changed/updated drivers but no good. All other USB devices are operating fine. The TS was also working fine when I shutdown the carputer, unplugged all wires, moved the carputer in the car by a foot, plugged everything back in and turned it on to test and problem started. Screen is in the dash so it did not move at all, nor did the cabling, except for connecting and disconnecting. I am thinking maybe the controller has gone bad but how do I test it? Can it be a software issue? - Help!
