That was the conclusion, however, based on the current conversation on the linux-usb-devel list, with the Ubuntu and Red Hat developers telling us of all of the problems that were caused when they did it, I think we should hold off for now.
My usb printer stops working too. A few seconds after loading usblp the device goes away and lsusb doesn't even show it, then it appears again after a few second because lsusb triggers a scan, usblp finds it and then in a few seconds it's gone again. Initially I set support_autosuspend=0 in usblp.c to work around it. If you've patches to test let me know.
Independant of everything else, your printer must be blacklisted. Please give me vendor:product.
