When testing HPLIP I found out that CUPS backends can access my printer only when they are running as root, when they are running as the special user lp, as it is usually the case, they cannot access the printer.
So I tried to find out why and saw that the /dev/bus/usb/*/* device file for the printer has group ownership "audio" and not "lp":

There must be a bug somewhere in the UDEV rules. |
