Hi. I have an 7" Touchmate e-Tab TM-MID780 tablet with android 4.0.3. The problem is the USB port doesnt detect anything except for the mice that came with it. Now, I cannot connect a flash drive, a 3g dongle or anything that goes into the USB port for that matter, even though the box says it supports all of them. Is there anything I can change or modify or add an app to overcome this problem. I'd truly appreciate your help guys.
