According to the Xorg log[*], the keyboard uses 2 event devices
(in particular, due to that, I get many duplicate lines in this
log file: one for each event device). But the error I get in the
journalctl output is only for the second event device.

[*] The lines from /var/log/Xorg.0.log corresponding to these two
event devices:
