Comment 2 for bug 1576951

the workaround for turbo is to disable magic pad supporting.

And in Turbo, what caused rebooting is calling null function pointer hdev->hid_output_raw_report() [1]

Compare to Android behavior, that pointer is assigned in uhid module [2] , but Ubuntu touch did not go that way and just keep it NULL.

I also tried to skip calling hdev->hid_output_raw_report() then the magic mouse device could show in cat /proc/bus/input/devices [3] , but nothing show in evtest [4] and no mouse courser shown on device screen.
