It would be nice to summarize the reason of the problem and
the currently working solution for further reference in the
mailing list (instead of just referencing external sources
that might disappear). ;-)

X.org as of February 2020 now requires UDEV (as known from
Linux) to discover input devices, this is the default now;
FreeBSD's devd can still be selected when building from source.

====> Backend to use for input device configuration:
      you can only select none or one of them
      DEVD=off: Use devd for autoconfiguration of input devices
      UDEV=on:  Use udev via libudev-devd for autoconfiguration
                of input devices

Involved parts to be updated or (re-)installed are xorg-server,
libinput, xf86-input-libinput, and libudev-devd.
 
Further information can be found in xorg-server's pkg-message.

Especially the new pitfalls for dealing with PS/2 keyboards
and mice, or stuff that you might need as a partial configuration
file into /usr/local/etc/X11/xorg.conf.d/, or possible additions
to /etc/sysctl.conf (values explained in /sys/dev/evdev/evdev.h),
or yet another way to set your keyboard layout, and a few other
Linuxisms are discussed in the forum thread mentioned above.

Please correct and advise if I didn't understand it correctly!

Vlad: As there seem to be more than one solution and suggestions,
which one worked _for you_? It's always nice to see a _verified_
solution on the mailing list where a real person can confirm
that a specific (!) set of actions solved the problem. :-)
