Add a graph with 4 output endpoints to this hub binding to support the scenario where a downstream facing port is connected to a device that isn't a connector or a USB device with a VID:PID. This will be used to connect downstream facing ports to USB type-c switches so the USB superspeed and high speed lanes can be put onto USB connectors.
