Bug#366845: libsane: Only root can use canon_pp backend

Package: libsane Version: 1.0.17-3 Severity: normal I've been trying to use my Canon N640P. It works very well when I run as root, but when I run as my normal user, sane can't find the scanner. When I run scanimage -L as root, I see: device `canon_pp:parport0' is a CANON N640P flatbed scanner
