To make suspend/resume work properly for USB the USB host controller must
be told to change state.  I thought I'd implement this (since it so annoying losing
the mouse every time you suspend).
But I can't seem to find any way for the driver to get notified when a suspend/resume
is about to happen.  Is it the case that there are no such mechanism in the kernel?
Or am I just blind today?
