udev not assigning group correctly for scanner

[<briand@aracnet.com>]

device `epson2:/dev/sg1' is a Epson GT-9700 flatbed scanner

crw-rw----+ 1 root root 21, 1 Jul 14 18:57 /dev/sg1

here's the rule it looks like it should be matching :


# Epson Perfection 2450 | Epson GT-9700F | Epson Perfection 2450 PHOTO
ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="0112", MODE="0664",
GROUP="scanner", ENV{libsane_matched}="yes"

Because, you know, that's the scanner I have :-)

So I'm not clear on how I can figure out whether a rule was matched at
all, and if it was, which one was matched.

Also, what's the best way to add rules to /etc/udev to force "my" rules
to be checked first.  Do I simply add a rules file with a low prefix
number ??

Thanks,

Brian
