The device exists for some years now, but it was never functional and it is not yet mentioned in the docs. After studying Linux kernel sources and a lot of tests it is now usable. A configure option doesn't exist, so it must be enabled in config.h. At runtime it is only loaded if the mouse type is set to 'bus'.
