Oh, that reminds me... there seem to be no length checks on any of these
functions. In this case I think it's OK because we've already checked
the length of usblp->device_id_string when we fetched it, but I couldn't
actually find an example which showed me an snprintf and the length I
_should_ be checking against, which made me nervous...
