That is true. But the output formatting is still improvable.

What about a layout like this:

hub.0
 \ virtio-net-pci.0: ...
 \ virtio-net-pci.1: ...
 \ user.0: ...
hub.1
 \ e1000.0: ...
e1000.1: ...
 \ user.1: ...

ie. printing the hubs first, listing all the peers of their ports
underneath them. Also, things like "type=(null)" should be avoided.
