I recently have bought for myself a Wacom Inutos Comic CTH-490. It is reacting to touch and the standard config ist working. On the opposite side in the Ubuntu System Settings/Wacom Graphics Tablet, there is not tablet detected. As far as I read there are no known problems with this tablet. I am running Ubuntu 16.10.
Drivers xf86-input-wacom and libwacom were compiled by hand with guidance by http://linuxwacom.sourceforge.net/wiki/index.php/Main_Page.
Following outputs are for the following commands:
lsusb: Bus 001 Device 006: ID 056a:033c Wacom Co., Ltd
uname -r: 4.8.0-41-generic
ls /dev/input/wacom/*: ls: Zugriff auf '/dev/input/wacom*' nicht möglich: Datei oder Verzeichnis nicht gefunden (Says it ist not there)
xsetwacom --list devices:
Wacom Intuos PT S 2 Pen stylus id: 12 type: STYLUS
Wacom Intuos PT S 2 Finger touch id: 13 type: TOUCH
Wacom Intuos PT S 2 Pad pad id: 14 type: PAD
P.S.: When running sudo add-apt-repository ppa:doctormo/wacom-plus my Ubuntu apt update says: E: The repository 'http://ppa.launchpad.net/doctormo/wacom-plus/ubuntu xenial Release' does not have a Release file.
This is most likely this bug:
