Thanks. Just to make sure that it's the culprit, can you back out
the patch for the usblp from the 2.6.30-rc6-00065-g3633832, whatever
that is? We only had one since 2.6.29 (attached).
Also, I'd like to see a usbmon trace. I don't want to create more
quirks, so perhaps we can work out some kind of compromise that lets
BJC-3000 work with the general code. Failing that, we'll add a quirk
and that would hopefuly restore your case (HP CP1215, I take it).
