Lukasz Bruun' s comment shows that the CUPS "usb" backend (this one feeds "lpinfo -v" with information) looses track of the printer whereas the printer stays visible for the kernel and the rest of the USB subsystem.
So for me it looks like a bug in the "usb" backend. Will report it upstream ... -- Brother HL-1430 USB printer will only print once https://launchpad.net/bugs/57050 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
