Details

The device works, but is not detected by the GNOME/Unity/Cinnamon control panel (a "No tablet detected" or "No stylus detected" message).

Description: This is most likely due to a missing tablet definition in your "libwacom" database. The GNOME Control Center (as well as its Unity and Cinnamon forks) relies on this database to get information about your tablet like how many buttons are present, if it is integrated into a display, etc. If your distribution ships an out-of-date version of this database, the control panel will display a "No tablet detected" message. This often happens to users of tablets newer than their distribution and tablet PC users.

Steps to take:

1. Run libwacom-list-local-devices. If your tablet is listed, the libwacom database recognizes your tablet and you have a different issue (note that the "Wacom Serial Tablet WACf0004" entry that is sometimes printed out is probably not your tablet, unless you are using a very old tablet PC). In this case, you might be affected by this well-known Ubuntu issue. If even that bug does not seem correct, please file an issue upstream.

2. If your tablet wasn't listed, search the libwacom bug database for your device and file a new issue if not found. We'll let you know if the latest version of the database includes your tablet, or if we need to make an update.
