I'm looking for an explanation of how these two things are structured in XP.
Not deep technical details such as the USB spec, but a block-diagram
description of why I need one of each for each USB port. I've scoured the
web, but there are too many hits to search them all...

Any ideas?

Thanks, but neither of my key terms is mentioned there, and the best-looking
links at the bottom are dead. Actually, that's where I started my search.
The wiki explanation skips this bit of detail, too. This is the
trouble...nobody explains this concept. What's the diff between a root hub
and a host controller, how are they related, why one of each in Dev Mgr?

:-)

Thanks, that's very interesting stuff. I'll have to chase that guy down, he
knows what I want to know. :-)
