Did you use any voodoo?Or Did you just plug and play?
I think it took a little magic. Cleaning cache, unpairing OUYA controller, then turning off OUYA and connecting PS3 controller, disconnected power, reboot, etc. Probably a little overkill but I so wanted it to work.
Wow! Neat. I did read around the PS3 is more compatible than the XBOX 360 :)
