I only have one 1950, so I'm not concerned, but that command produces
the same exact output as the one I posted --- no serial number. My
only thought is that I didn't compile the DVB stuff, just the analog
half. Maybe that information finds its way into udev via the DVB chip
drivers?
Your output doesn't have any 'parent' information? I pasted mine below
(notice the lowest entry is like yours).
I do have the full driver DVB/Analog configured so maybe that is a
different but I wouldn't think likely since this stuff appears in the
device configuration space. Or maybe it is a different version of the
udev stuff. I am running Fedora 12 on my server.
Output: udevadm info -a -p $(udevadm info -q path -n /dev/video0)
Udevadm info 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.
