Created attachment 246393 [details] required udev rule this is the rule taken from the ubuntu pkg which belongs to /lib/udev/rude.d/
xf86-input-wacom doesn't install udev rules by default, since I believe that's all handled by the Xorg server these days. I'm not intending to deviate from upstream to provide specific rules, so I'm going to mark this as WONTFIX. Please feel free to reopen it if you feel strongly on the matter...
