It works on older releases, but with the Lakka-Generic.x86_64-devel-20151207162558-r21226-gaa8871a.img and Lakka-RPi2.arm-devel-20151207161710-r21226-gaa8871a.img it doesnt even work with the usb-cable. I can connect the 2 controllers to my bluetooth dongle with bluetoothctl but no buttons work.
Wuzzap?
