Please add the line /dev/bus/usb/ r,
to the /usr/sbin/cupsd section of /etc/apparmor.d/usr.sbin.cupsd. Very important is the slash in the end of /dev/bus/usb/. After that restart AppArmor with sudo /etc/init.d/apparmor reload and return CUPS into enforce mode: sudo aa-enforce cupsd USB printing should now work correctly. I have committed this fix to the Debian BZR repository of CUPS. Will be part of the next CUPS package. ** Changed in: udev (Ubuntu) Status: In Progress => Fix Committed ** Changed in: udev (Ubuntu) Status: Fix Committed => Triaged ** Changed in: cups (Ubuntu Karmic) Status: Triaged => Fix Committed ** Changed in: udev (Ubuntu) Status: Triaged => In Progress -- usblp Kernel module needs to be removed and /dev/bus/usb/*/* made accessible for USB printers to work with CUPS 1.4.x https://bugs.launchpad.net/bugs/420015 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
