matching udev attribute keys

[<briand@aracnet.com>]

Hi all,

how do I know that "SerialNumber" is a valid udev key other than
the fact that it is listed in dmesg when the device is plugged in.

I cannot for the life of me get a udev rule for a device to match on
the serial number, even though the number is in the dmesg file.

I know that my rule works because I removed the SerialNumber attribute,
and matched on the KERNEL device only, which worked flawlessly.

I've notice that 

sudo udevadm info --query=property --name=/dev/disk/by-label/NAME

produces 

ID_SERIAL
ID_SERIAL_SHORT
etc...

none of which seem to match what I find in the rules files, e.g.
SerialNumber.

Can someone bridge the gap ?

How do I ensure that the ATTR keyword I use is something that udev will
really match on ?


Thanks,

Brian

P.S. yes I've tried using ATTRS{ID_SERIAL_SHORT}, etc..., WHICH IS FROM
udevadm info, and nothing other than the kernel device works.  However
the information IS showing up in the dmesg output. ????
