Verify if the tablet does not work and then run sudo rmmod wacom and then sudo modprobe wacom
In some cases it depends if you are on Wayland session or X11 session.
On X11 you can install xf86-input-wacom package and then via xsetwacom --list devices you can see more about your tablet being or not recognized as connected, then check to set things up via Settings.
My tablet (different Wacom model) wia USB works just fine, but i always have to either turn it off then on after boot, or disconnect and reconnect it to have it working properly. It was so since kernel 4.5 up …
Maybe you are using TLP and interferes somehow …
