Most Trogdor devices have two USB type-c ports (i.e. usb-c-connector nodes), but Quackingstick only has one. Also, clamshell devices such as Lazor have a USB webcam connected to the USB hub, while detachable devices such as Wormdingler don't have a webcam, or a USB type-a connector. Instead they have the pogo pins for the detachable keyboard. Fully describing the topology like this will let us expose information about what devices are connected to which physical USB connector (type-A or type-C).
