Working on getting a Huion drawing pad working on a laptop.

# uname -a
FreeBSD ayo 12.1-RELEASE FreeBSD 12.1-RELEASE r354233 GENERIC  amd64

I followed the directions at:
https://wiki.freebsd.org/WacomTablet

Any pointers on getting this working? It seems the device is added to
/dev/input/event* and also /dev/ums1, /dev/ums2.  If I add to Xorg
manually, ie.

Section "InputDevice"
        Identifier      "Huion on wacom pad"
        Driver          "wacom"
        Option          "Type"                  "pad"
        Option          "Device"                "/dev/input/event7"
        Option          "AutoServerLayout"      "true"

It appears to add it in Xorg log, and It shows up "sometimes" in
programs like GIMP but doesn't actually work. Without the manual
config it doesn't appear in xorg log. But I think it's supposed to
used devd/HAL anyway, without any config.

using 'event7' isn't ideal but the # changes on reboot anyway.

If I change the device to /dev/ums1 and 2 then Xorg log:

Huion on wacom pad: Error opening /dev/ums2 (Device busy)

This device works when plugged into a debian laptop.
