I have a apex tm772 tablet and unity 4 remote is not working on unity 5.1.1 and I have followed all the tutorials i can find, usb debugging is on, wake, and mock location.
It may be because windows cant find the usb drivers for the tablet when i plug it in. But i have the android google usb driver installed. At the moment the device shows this.

I cant even find usb drivers for this particular tablet.
