Hi.I have a rockchip apad with, I think, a blue led (even though it is red) that I had to flash with the 5.1 blue firmware.( the others didn't work)The USB nearest to the sd card works, but the one near the headphone socket doesn't do anything.Is this faulty, or is it used for anything else?Thanks.

Apparently you need to enable it. Not sure how.

For me (aPad 2nd batch red LED) it is a normal OTG usb port.I can connect mouse and keyboard without problems.//EDIT: to activate this go to 'settings' -> USB Mode select -> HOST MODE (activate it)
