Your device needs to be able to get on and off the bus based on the
signals on the port, you can't just use gpio to read it and then pass
the data back to the pc and have it then send a command to change it.

That part has to be done locally on your device, probably a gal.

Do you think you know enough, to be able to implement this? Or is it
just a random question?
