Ah well. sorry it didn't help.  But I have to admit that I'm using an
older version of the Xserver: xorg-server-21.1.8_5,1.pkg and probably
an older version of libinput: libinput-1.24.0.pkg

I also have xkeyboard-config-2.40_3.pkg and libudev-devd-0.5.2.pkg installed.

I'm also using the NVIDIA driver; don't know whether that makes a difference.

And I have these devices in my kernel config file:

device          atkbdc                  # AT keyboard controller
device          atkbd                   # AT keyboard
device          kbdmux                  # keyboard multiplexer
device          ukbd                    # Keyboard

But I see that you also have the keyboard multiplexer, so I guess you also
have these devices.

My output looks the same, my keyboard is a little older.
