Oh cool, someone talking about the really weird bug that I've never seen reported elsewhere. Seems like an issue where certain versions of Unity (to name one engine) doesn't like it when your actual game controller is the second joystick it detects. Not really Keychron's fault or Linux's fault, just a weird engine quirk.

Anyway, if someone finds this by searching, at least on Arch it's as simple as adding a custom hwdb entry at /etc/udev/hwdb.d/61-input-id-local.hwdb:

  id-input:modalias:input:b0003v3434p0283*
   ID_INPUT_JOYSTICK=
and then run systemd-hwdb update.

The modalias value is found at /sys/class/input/<yourdevice>/device/modalias
