So it can have more that 1 port? At least for the bindings, I think you
should combine these 2 bindings. Whether the driver should be combined
is separate question. I imagine you have 2 compatible strings because
you have 2 drivers, but that isn't really a reason to have 2.
I still have no idea what SCU is.
