SunFounder didn't provide a 4-pin touchscreen USB cable, so of course the touchscreen can't work. They "guarantee" that they will contact the buyer within 60 minutes. I've been waiting for almost two weeks and they still have NOT answered me. You just have to tell me how to buy a cable. The device may be great, but SunFounder lacks integrity; If they don't contact me I'll have to return a potentially good product for only $3 cable. I strongly recommend staying away from the SunFounder line of products.
