You definitely need to be in mode a for it to work, does your moga pro not work in a? I have a moga pocket which only supports mode a and it works on Real boxing. Are you having trouble connecting in mode a? It can be a major pain in the ass to use the moga on OUYA because it can be really hard to get it connected. You'll want the controller and ouya right next to each other and I found its easier to connect after a reboot.
