Your posted information ("lsusb" reports printer, "ls -l /dev/bus/usb/*/*" shows that UDEV has set correct permissions, but /usr/lib/cups/backend/usb does not list the printer) matches exactly with bug 872711 which I have found and reported today. It is a kernel bug which affects many printers of different brands, but not all printers. Marking as duplicate of that bug ... ** This bug has been marked a duplicate of bug 872711 Kernel does not report some USB printers correctly, making them not being detected by CUPS -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/865613 Title: Local Epson printer R300 not recognised To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/865613/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
