APC BackUPS CS 500 and NAS4Free


Trying to connect APC BackUPS CS 500 to NAS4Free ( - Sandstorm (revision 847)) with no success?

dmesg shows:

ugen0.2: at usbus0

but after enabling UPS service you see:

Broadcast Message from root@doodlenas.local
(no tty) at 9:36 CET...

Communications with UPS ups@localhost lost

3 things.

1) Make sure that your 'domain' general setting is not an empty field.

2) Do a system restart after connecting UPS and enabling UPS Service

3) Do NOT trust official driver compatibility list which tells to use usbhid-sys as a driver


To confirm that type:

# /usr/local/libexec/nut/usbhid-ups -a ups -D

doodlenas: ~ # /usr/local/libexec/nut/usbhid-ups -a ups -D
Network UPS Tools - Generic HID driver 0.37 (2.6.5-Unversioned directory)
USB communication driver 0.31
Error: UPS [ups] is for driver usbhid-sys, but I'm usbhid-ups!

and set:

Save and....

Voila! If only that information was visible in log before.
