Not sure. We have an early version of one where I work (game dev), and to my knowledge it requires the steam DLL, and doesn't expose XInput/DirectInput bindings (I wasn't the one who added support for it, so this could be a lie, and it could have changed by now).

I wouldn't be surprised if it was similar to Wacom tablets. Wacom tablets out of the box you get a generic pointing device (a mouse input). If you want the touch/tilt sensitivity you need to install their drivers. This was on Linux years ago, so my memory could be wrong or things might have changed. It actually makes it a bit confusing because you can't tell if you're getting a pointing device or a pressure sensitive output easily.
