I can't translate that description into behavior.

Is this basically turning the controller off, so that resume
sees a controller reset and everything re-initializes?

Or is it a real USB suspend state, from which the OHCI
controller can issue system wakeup events, and which
preserves device power sessions?

One test is:  plug a device in while the system is
suspended.  Does that wake the system up?

Another test is:  suspend while a device is connected.
Unplug it; does that wake the system?  Re-plug it;
that should *always* show up as a new device when the
system resumes (different USB address etc).
