I cured the seg fault by doing an apt-get install cupsys. Although, I always thought regular apt-get update/upgrade would keep me up-to-date. However, this, or my move to kernel 184.108.40.206, appears to have changed the /dev usb layout. There is no /dev/usb/ lp0 or /dev/usblp0 any longer. In fact, when Turboprint 1 is selected for local port, it only provides /dev/lp0. I have found the following in /dev:
dev/disk/by-id/usb-Canon_iP6700DStorage_130D8B-0:0 --> sdb
I created the uri usb:/dev/sdb for the printer, with no success.
Again, my version 1.96-3 of Turboprint is not capable of finding out the printer is usb in setup. Does this mean that my distribution/kernel upgrades have made my system incompatible with version 1?
