Hi,
I do not use wacom tablets so it is just simple troubleshooting
hints that maybe you already did:
1) check if xserver-xorg-input-wacom package is installed otherwise do:
apt-get install xserver-xorg-input-wacom
2) you can add a conf file in /etc/X11/xorg.conf.d/wacom.conf
Section "InputClass"
Identifier "Wacom Tablet"
MatchProduct "Wacom Intuos4"
MatchUSBID "056a:00b8"
Driver "wacom"
EndSection
3) check if the usb port is oxidized
4) check if there is any udev rules that run when the tablet is inserted.
This rules can be modified at your liking running some script
that sets the wanted options when the device is inserted.
See https://forums.linuxmint.com/viewtopic.php?t=363716
Hope this helps,
Ciao,
Tito
