terakin, LiaM, can you run the command lpadmin -p <printer> -o usb-unidir-default=true
in a terminal window, with "<printer>" replaced by the name of your print queue (print queue names are shown by the "lpstat -v" command. Then remove all stuck jobs from the print queue and turn off and turn on the printer. Does the problem go away now? If not, try the command lpadmin -p <printer> -o usb-no-reattach-default=true clear the print queue and power-cycle the printer. Does it work now? If yes, try to remove the first workaround via lpadmin -p <printer> -R usb-unidir-default Does it still work? To remove also the other workaround run lpadmin -p <printer> -R usb-no-reattach-default Please post also the output of the command lsusb This way we get the USB IDs of the printer to be able to add permanent exception rules to the CUPS USB backend. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/997040 Title: usb printer backend hangs when usblp kernel module is loaded To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/997040/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
