The following short transcript is from adapting the udevadm invocation in http://wiki.debian.org/udev to investigate 1394 support in my Squeeze system. Two questions.
* What exactly is meant by "device specified by the devpath" in the output? According to the udevadm man page, devpath is the value assigned to --path; but that parameter is not present in the command below. No devpath is specified. * What exactly is '/class/ieee1394_protocol/raw1394'? /class is not a directory in the filesystem and /dev/raw1394 is the only 1394 device I've found. Thanks for any ideas, ... Peter E. ======= transcript======= joule:/dev# udevadm info --name=/dev/raw1394 --attribute-walk Udevinfo starts with the device specified by the devpath and then walks up the chain of parent devices. It prints for every device found, all possible attributes in the udev rules key format. A rule to match, can be composed by the attributes of the device and the attributes from one single parent device. looking at device '/class/ieee1394_protocol/raw1394': KERNEL=="raw1394" SUBSYSTEM=="ieee1394_protocol" DRIVER=="" joule:/dev# ls /class ls: cannot access /class: No such file or directory joule:/dev# ======= transcript======= -- Carnot is down, waiting for installation of NetBSD.
