It may not be possible to do what I'm about to suggest with this rule
(unless there's a way to match on all devices that have an
authorized_default file -- I'm not sure where in the USB stack those
devices are), but for this rule:

>> /sys$DEVPATH/authorized'"
(and the one below it), can't you just do this instead of the RUN?:
ATTR{authorized}="1"
Or does that not work for some reason? (It'll prevent spawning a whole
lot of shells to do work that udev already has code to handle...)
