[Nut-upsuser] Belkin F6C1100-UNV not recognized by megatec_usb?

[David Mohr]

Hi everyone,
I have a belkin ups that was bought around 2 months ago. It seems like
the driver doesn't like the UPS, although on the website it's listed
as supported. This is on a gentoo system with nut 2.2.1 .

megatec_usb output:
---------SNIP----------
digamma nut # ./megatec_usb -a belkinm -DDDDDD

So did something change in the ups? I have a couple of older belkin
ones on different computers that do work fine with nut, and then again
a couple of ones that don't. This one is on an important server, and
we have had power outages lately because of construction close by...
:-( I'd really like to get it working. Does anyone have ideas on what
I can do next to debug this problem?

Thanks,
~David
