SubjectRe: 2.6.3-bk9 QA testing: firewire good, USB printing dead

I have this identical problem using a 2.6.3-bk snapshot from a few days
ago. My hardware is a Samsung ML-2150 printer (USB 2 High Speed)
connected to a VIA EHCI embedded in my VIA KT-600 chipset.

I sent a four page print job through CUPS; during page 4, the printer
timed out, and the CUPS "usb" process was hung and would not respond to
any signals (not even -9). When I unplugged the printer's USB cable, the
"usb" process died, and my syslog reported these error messages (but not
before I unplugged the cable). In my case I had 3,458 of them.

Plugging the printer back in, usblp re-registered it, so I tried sending
a job again, but could not get any data to flow to the printer without
restarting the Linux system.
