Hi everyone! I really need som help before I get crazy! I cant seem to get my Usb ports to work on my tablet. Neither external disc, modem, or anything with an usb seems to work on the tablet. It doesent respond at all. What is it that I am doing wrong? Tryed everything and cant find a resolution Its the one with 2 usb and 1 sd card. I hope someone has the answer... Thanks!!
