Thank you all for the additional logs and info of your situation. Note: The attached binary file is NOT the libusb-based USB backend of CUPS 1.4.x. It is the unpatched USB backend of CUPS 1.3.9, with a bug fix patch which was added between Intrepid and Jaunty removed.
It looks very much like a slight change in the kernel which breaks compatibility with the USB backend of CUPS. So most probably you could work around the problem by using the HPLIP backend (most HP printers) or the HAL backend. When creating new print queues system-config-printer selects the HPLIP backend automatically wherever possible. The HAL backend can be selected maually by clicking "Connection" at the bottom of the right part of "Select Device" step of the new printer wizard, when in the tree view on the left a USB printer is selected. Next step to try to fix this problem is to replace the CUPS USB backend by the libusb-based one of CUPS 1.4, as it accesses the printer through another entrance point in the kernel, the same ways as the HPLIP backend does but for printers of all manufacturers. The automatic printer discovery/setup via HAL (hal-cups-utils) is already prepared for this backend. -- Printer (HWModel Name) May Not Be Connected https://bugs.launchpad.net/bugs/348316 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
