I really think the isight thing is a totally different thing entirely.

And quite frankly, that's just a BUG in the USB implementation. If the
USB ID changes, it shouldn't be considered a "resume" thing at all,
but a probe thing, and that should not be done in early resume - it
should be done *after* the resume is done.

The fact that USB confuses resuming existing devices and probing new
ones is just an implementation issue, and is a bug.
