This problem will be solved in Ubuntu Precise (12.04). We have a vastly improved USB backend for CUPS there which does not require any more to blacklist the usblp kernel module. this way the module stays present and assures compatibility with proprietary legacy backends provided by printer manufacturers. In addition, the CUPS USB backend uncouples a printer from the kernel module only while it is accessing this printer and recouples the printer after the access. This way kernel-module-based USB printer accessand libusb-based access live perfectly together. On one computer a printer using a proprietary kernbel-module-based backend and a printer using the libusb-based standard backend can be used in parallel (they can even print at the same time). One and the same printer can even once be aceessed by a proprietary backend and another time by the standard backend (using two queues).
In Precise this bug is fixed. Closing ... For Oneiric try the CUPS package (plus cups-filters) in my PPA: https://launchpad.net/~till-kamppeter/+archive/ppa Keep "usblp" in your /etc/modules file as described in comment #11. Now both printers should work. ** Changed in: linux (Ubuntu) Status: Confirmed => Fix Released ** Package changed: linux (Ubuntu) => cups (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/902970 Title: /dev/usb/lp0 missing after update to 11.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/902970/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
