I have a tablet that says ZTPad 7" Wi-Fi Touch Screen Tablet on the box. The about portion of the tablet says the model number is ZT ICS, android version 4.0.3 kernel version 2.6.34 root@android #1818. I can't get a thumb drive to work with OI file manager, and furthermore, once i plug it into the tablet, it must be reformatted on a pc (windows or linux) in order to work again. I have tried pluggin into the port that says device (as in put device here?), and the one that says host (as in this is the host port?), but i still can't get anything to happen. Can someone walk me through this simple task?
