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

Hi Sergei, you can get udev debugging using: root at host:~# /etc/init.d/udev stop root at host:~# udevd ?debug 1288130388.961886 [26940] udev_device_new_from_syspath: ? This might shed some light into syntax issues.. Petr Kub?nek Sergei V. Dubrov p??e v ?t 21. 07. 2011 v 12:07 +0700:> G'day, all! > > It's my second trouble with NUT.
