The full range of Wacom STU signature pads is supported. Some of the models have reached end of production life but still require software support. As new models have been introduced additional functionality has been added and this is catered for in the Software Development Kits (SDKs). The interface specification is not publicly available and instead access to the devices is made through the use of an SDK.
