The remotes were the MyGica remotes supplied with the ATV1900AC unit. I recall the sales guy telling me that it comes with the KR54 (with volume up/down buttons) but I should get the KR301 also as it was a better remote. I'm worried that the 4 x USB ports in the unit have stopped working because I can't even connect a standard USB mouse or keyboard. Would really like a link to the original Android Version 5.0 firmware just to rule out a buggy OTA update which lacks driver support for my two remotes perhaps?
