Yes, i'm sure; the model is Rii mini i8+ bluetooth (the wireless model doesn't have the bluetooth button on the right, and i've connected it via bluetooth with a tablet, as a test)
Take the USB dongle out and try again, you don't need it.
But i'm not using the dongle (Q10 has bluetooth module).
Anyway, i checked on the Riitek website-support, and i found these hints:
"On some Android TV Boxes there is no standard Bluetooth HID (Human Interface Device) drivers required for Bluetooth i8 operation. Unfortunately some hardware manufacturers do not include in the firmware all the expected functionality of the Android operating system, but only a partial implementation of the Bluetooth functionality where the HID profile is missing for the management of the keyboards."
Maybe Q10 pro can't work with this bluetooth keyboard because of this...does anyone has got this keyboard (bluetooth version) and can confirm it?
