If you have CUPS 1.4.0 already, the USB problem is caused by a new USB CUPS backend. For this backend the "usblp" kernel module must be unloaded.
Edit /etc//etc/modprobe.d/blacklist.conf adding a line blacklist usblp and then run the command sudo rmmod usblp Now CUPS should see your USB printers again. -- [karmic, regression] Printing with HP Laserjet 4100 broken https://bugs.launchpad.net/bugs/419143 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
