This is a null input driver for the XLibre X server.
It doesn't connect to any physical device, and it never delivers any events. It functions as both a pointer and keyboard device, and may be used as the X server's core pointer and/or core keyboard.
Its purpose is to allow Xservers pre-version 1.4 to operate without a core pointer and/or core keyboard.
