On Lucid Lynx 10.04 after updates I was having the same problem. My dmesg had the line: [ 279.196192] usb 4-1: usbfs: interface 0 claimed by usblp while 'usb' sets config #1
and "usblp" module was still loaded. I solved everything by blacklisting the usblp module, but not chmodding the /dev/bus... files. I used these commands (as root): echo "blacklist usblp" > /etc/modprobe.d/blacklist-cups.conf rmmod usblp /etc/init.d/cups restart update-initramfs -u should we file a new bug? -- 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
