Please take a look at the 'udev' branch of system-config-printer: http://git.fedorahosted.org/git/?p=system-config-printer.git;a=shortlog;h=refs/heads/udev I'm trying to use libudev to read the ieee1284_id attribute but am failing. The devpath I'm given is: /devices/pci0000:00/0000:00:1d.3/usb5/5-1 I can see that the file I need is: /sys/devices/pci0000:00/0000:00:1d.3/usb5/5-1/5-1:1.0/ieee1284_id but I can't see how to get to it. How do I find out the name "5-1:1.0"? (The code is currently trying usb_interface which is obviously wrong.) Tim. */
