in /sys/kernel/debug/hid I have two devices for the keyboard. One is 
0003:060B:0230.0002 and the other 0003:060B:0230.0003

attached are the rdesc files for both devices.

I only get events for the working keys on the *:0002 device.
All other files were empty after I pressed some keys.

The events for the working keys are attached in the *.events file.
I first pressed backspace and then the menu key.
