Nvidia Shield Controller, Keys presses not identified

[rajil]

Hello,

I have a Nvidia Shield Controller paired via bluetooth to Arch Linux PC. The controller appears in the sc-controller registration list. However, when added the controller any keypresses on the controller are not identified.

Here is a debug log

$ sc-controller -d -v

I'm afraid debugging this issue without actual Shield Controller is not going to be easy. Does controller works with evtest? What's its output?
