Well, I wouldn't need much more than "OHCI controller as USB bus #1" or
something like that. Just something to identify the type of controller
and perhaps a bus number. Then I could look at usbview and see for my
three controllers:
OHCI controller as USB bus #1
UHCI controller as USB bus #2
UHCI controller as USB bus #3
And be able to differentiate between devices which are on different parts
of the tree. Tho more information (io ports, irq, etc) might be
interesting to have.

True enough. That's mostly why I posted about this instead of trying it
myself. I don't suppose you're volunteering? :)
