I put the rule at /etc/udev/rules.d/23-usb-rules, which comes before the

This is not true.
Just to clarify, the later rules will continue to process and they are
cumulative. This has been the case for some time now. I don't remember
the version where it changed, actually I think it was 057, but I'm not
sure and it doesn't matter anyway. To get the old functionality, you
can add 'OPTIONS="last_rule"' to the last rule that you want to be
interpreted.
And this is where it gets hairy for me, but if I understand it
correctly, that option could have a nasty side effect. ISTM that rules
need to be very specific if you use it, else you may break something
else down the chain. IOW, I _think_ that a very open rule, like one
that contains just a subsystem, a group, and the last_rule option, could
choke the rest in the chain that match the subsystem, but I'm not
positive. Others probably know better than I, but I felt an explanation
was in order as opposed to the strait answer. I've been very careful
with that option on my own system, but if anybody can confirm or deny my
suspicion, it'd be appreciated.
