This is how R5 gets USB games devices today and also SB-Live GamePort
devices.

The Gameport "driver" sends the information that a game devices are
generating to BJoystick and this part are not type (type as GamePort, USB)
dependent.

I do think that wee need the "driver" but with some modification, like not
publishing devices you don't have as it does today.

Actually there's no way to tell if a joystick is connected to a gameport, unless some proprietary extensions I don't know of. Also, the port support 4 axis and 4 buttons, so it is possible to have 2 joysticks with 2 axis and 2 buttons each with an Y-splitter cable; but it doesn't work with all the ports and all the joysticks. Over the years, makers such as Microsoft and Logitech used the game port in _very_ creative ways...

An ideal design for a game port driver would be to just publish the ports and just report the raw readings, then let the user create the joystick device by let him choosing which port it is connected to. This approach allows for different uses, back at school we used it in some electronics projects.
