I had purchased a Sainsmart 9 inch touch screen (http://www.sainsmart.com/raspberry-pi/s ... ry-pi.html) a while back and cannot seem to get the touch screen to work at all, the display itself works fine, but when the touch screen is plugged in it does not sense any contact. I have not been able to find any help online and their tutorial is not helpful.
Any help is greatly appreciated.
