That's not how the USB implementation works.  Although a timestamp like 
the one you describe is going to be added.

I sort of like this idea -- it seems that it is low overhead.
Of course it requires every device driver to be changed.
Instead we could maybe hook the generic driver entry points
and do this in the framework -- dunno if that is viable.

No, you can't get around changing all the drivers.

Generic entry points are for _system_ suspend, and if you try to abuse
them for runtime PM, you'll have to audit/change all the drivers.

Is this your position regarding USB autosuspend, too? Should we use
other methods than suspend/resume?

PS: Do we have _two_ pm lists?
