I have recently bought a Wacom CTH480 (Intuos pen and touch small) (I am using Ubuntu 13.04 --64 bit)
The Wacom Graphics Tablet application present under System Settings is showing "No Tablet Detected".
lsusb detects the Wacom device as connected, but
xsetwacom --list devices shows no output.
The light (white) itself on the device glows when connected to the computer and other light (blue) glows when the stylus is brought near to the active area. The mouse pointer does not move when the stylus is moved over the active area on the tablet.
I have visited some forums discussing the problems relating Wacom tablets and the Linux Wacom project, but got nowhere on how to start troubleshooting the problem.
Any help will be greatly appreciated.
