I'll do more tests this week-end and see if I can come up with a patch doing what we said that works (at least with no device plugged, currently, I get problems even without anything plugged, but I haven't had much time to dig further than the root hub problem).
Great -- I look forward to your results!
Likely that last round of PM updates will improve some things. Before the previous patch, I know at least D3cold suspend/resume worked right both with and without devices connected, using APM to drive the PM machinery. I don't know about D3hot (HC retains power); I could believe other trouble lurks there.
