OK well before I rewired my whole system. I noticed that the USB plug comping from the xenarc had to be in the same port inorder for the touchscreen to work. THe PC has been outta my car for a couple days cuz i rewired everything. I go to connect everything back and nothin! MY touchscreen wont work...I have put it in the same port and everything thing. I tried reinstalling the drivers....different USB cable....It is connected straight to the mobo....I cant seem to get it to work now! Everything else works fine!
