Ah. A root hub is an invention of the usb std. There's no such thing. It's the controller. It can be that usbd does not write vid/did for root hubs, perhaps.
I've not seen a root hub in a keyboard. If it's a usb keyboard, it can't be a root hub, because you have to plug the kbd into a port, which belongs to a hub, root or not.
