Thanks for sending this in. Unfortunately, Casio has marketed (at least)
two different cameras with the same device ID numbers. One of them
requires the Protocol entry and the others (like yours) don't.
Matt, this patch will prevent those messages from being printed. It's an
ad-hoc approach, but until another device exhibits the same sort of
difficulties we can live with it. Besides, this whole business about
logging unneeded unusual_devs overrides was only intended as a temporary
scheme for finding out what entries can be removed.
