Each root hub necessarily is a unique device, representing a set
of downstream links. Unless Peter didn't test something relevant,
it would seem we have observational proof that two root hubs can
share the same device node for an upstream link.
I can't think of a reason to demand multiple upstream links, though
sharing them between root hubs like that isn't a common structure.
