Same here on 9.10, I tried all kind of different things including
pinning CUPS and related dependencies from lucid, it always lead to the
same segmentation fault.
The only workaround that I found, to be able to use the printer again,
was to blindly add a printer from the CUPS admin page and point
I disabled the usblp kernel module.
When running /usr/lib/cups/backend/usb under strace, I get:
[...]
open("/dev/bus/usb/003/004", O_RDWR)= 3
ioctl(3, USBDEVFS_SETCONFIGURATION, 0x7fff4c1b19d4) = 0
ioctl(3, USBDEVFS_CLAIMINTERFACE, 0x7fff4c1b19cc) = 0
ioctl(3, USBDEVFS_SETINTERFACE, 0x7fff4c1
