Greetings! I recently bought myself an android tablet, and i have been trying to connect my USB keyboard to it. Whenever i plug it in, the tablet doesn't even acknowledge the device is there! I don't even get a message to tell me the usb device isn't recognised. I have tried many usb devices, and none of them seem to work. However, this micro usb port is the only usb port on the tablet, and is the same one used to charge the tablet, and that works absolutely fine. If anyone could let me know what i need to do, that would be a big help!
