So at what moment after a resume does a firmware that was in use with a
device go away and what do we do about devices inserted while suspended ?

Remembering that

- there is no moment when USB says 'we have finished re-enumeration'.
  There is no point at which you can say 'we have finished
  re-enumeration, we are now starting on enumeration of new stuff'. New
  stuff wanting firmware will pop up on resume mixed in with old stuff.

- we don't seem to have any device or bus infrastructure for doing a
  'post resume' purge of such data if we could decide when that moment
  is ?
