Hi Charles, thank you for your answer.

This was indeed the core of the problem. I have amended the configuration

It means now the communication works as required. Alas I now have another

Just for the record here is the configuration after the changes.

The configuration is as follows.


       driver = usbhid-ups
       port = auto

password = password  #password changed to demo
upsmon master

#upsmon configuration
RUN_AS_USER monuser

MONITOR eaton at localhost 1 monuser password master #password changed to demo7

# --------------------------------------------------------------------------
# SHUTDOWNCMD "<command>"
SHUTDOWNCMD "/usr/lib/web-admin/backend.pl power_off"

Which solves the question from this post. The syslog messages do not show

Unfortunately when testing the UPS does not power down. The problem is the
upsdrvctl cannot pass the command to the ups.

this is the message from  upsdrvctl

louis at b3:/etc/nut$ sudo upsdrvctl shutdown eaton
Network UPS Tools - UPS driver controller 2.4.3
Network UPS Tools - Generic HID driver 0.34 (2.4.3)
USB communication driver 0.31
Using subdriver: MGE HID 1.18
libusb_get_report: error sending control message: Device or resource busy
Got disconnected by another driver: Device or resource busy
Can't initialize data from HID UPS
Driver failed to start (exit status=1)

I unplugged the usb and replugged and start nutted again, no change.

Hope you can help a little more, Thanks so far.

Regards, Louis
