[Nut-upsuser] Udev rules troubles: incorrect ACTION expression?

[Sergei V. Dubrov]

G'day, all!

It's my second trouble with NUT. Latest nut-2.6.1.tar.gz installed from 
source on Xenserver 5.6 SP2, UPS is Powercom WOW--500U FW3.A4 (USB). 
Problem with setting permissions for udev (described in 
/etc/udev/rules.d/52-nut-usbups.rules file):

ACTION!="add|change", GOTO="nut-usbups_rules_end" don't work for me. Only 
when I changed ACTION to:

ACTION!="add", GOTO="nut-usbups_rules_end" (without |change) - it's began 
to set correct permissions 0664 for my USB UPS device as specified in 52-
nut-usbups.rules file. Default for usbdev is 0640 - it's insufficiently for 
non-root user:

#  PowerCOM WOW  - usbhid-ups
ATTR{idVendor}=="0d9f", ATTR{idProduct}=="00a4", MODE="664", GROUP="nut"

May be ACTION!="add|change" has incorrect syntax?
