Actually it might make some sense. In 2.4 we had a problem recently
where the interrupt pipe running to the external hub was not
activated. Without it, hub's brain melts down.
This case is likely to be a different story, because the camera reported
the unit attention and it would not be able to do it if the hub went down,
but the point is it's nothing out of ordinary for devices to fail when
hooked to a hub.
