Only one time witht the purchase of my Coby MID7012 tablet with the android 2.3.3 operating system did a wirwless mouse that has the wireless usb adapter work on my tablet when plugging in the full size adapter cable supplied, then it will never work again. I have been through Coby technicians and coby support personel and I was even told to do a factory reset, which I did, and zero results....Is there a compatible mouse / Keyboard that will work with my model, as the instruction manual shows that either is supposed to function using the usb connector. There is no OI manager to install so I can see the usb properties, as that seems to be only for the android phones and not tablets. The usb port does work as I can connect to my PC, but it will not display a pointer or recognize a flash drive. I read you have to format the flash drive to exfat, but I am more concern with having a external mouse / mini keyboard to function.
