[PATCH] USB: handle USB printer error bits independently
Some printers report errors (like out of paper or offline) without
setting the main "I have an error" bit. I see this on my home
printer and someone else has confirmed it for me, suggesting that
we check the printer error status bits independently, ordering
them as we see fit, so here's a patch that does that.
