The driver software must be installed for full and correct functionality of your device. For both Windows and Mac, the driver can be found online at Customer Support, or on the Installation CD (if included). Please note that the web driver package will almost always be newer than the version included on the Installation CD and is the preferred source.
After the driver is installed, the Wacom Desktop Center Updates section will indicate when driver updates are available.
If you have a pre-installed driver, your device will be ready to use. Refer to the Quick Start Guide that was included with your device for start-up instructions.
