Subject: USB usblp: rate-limit printer status error messages
Message-Id: <20050731204119.181d511a.rdunlap@xenotime.net>
From: Randy Dunlap <rdunlap@xenotime.net>

I unplugged my USB printer and almost instantly got several hundred
of these in my kernel message log:
drivers/usb/class/usblp.c: usblp0: error -19 reading printer status
