That's one piece to my puzzle!

So the device would appear to be /dev/hiddev0.

Yes, by USB standard definitions a ups _is_ an HID device.

I'll try that in the "nut" config file.

I'd think if it was usb, and because of that standard definition, nut should
assume /dev/hiddev0 as a starting point, scanning upwards till it finds the
right response or runs out of udev created devices. But I but haven't ever
used nut so that is just a SWAG.

Serial interfaces OTOH, at least in the belkins, seem to be all a very
proprietary thing, more of an individual item q&a session from my snooping,
and it doesn't seem to translate via a usb<->serial adapter to anything that
resembles a normal protocol. On my older belkin it would work with a pl2303
plugged into its serial port MOST of the time, with an annoying false loss of
comm message a few times a day, but then they found some problems with the
pl2303 code & the linux-usb people have managed to destroy what functionality
it had, so all of my adapters are now FTDI's.

And I will look for apcupsd.

I am in a rural area among cotton and soy bean fields and rely on
several UPS's.

Just yesterday afternoon the power was dropping momentarily with
lightning but this computer, using a different UPS, kept plugging along
oblivious to it.

I seem to collect old supplies, all except one so far have responded to
the replacement of batteries, this last one required two 12 volt, 7.5
a/h series connected gel-cells which seem to be common to most I've
acquired and can be had for about $7 each plus shipping.

Thanks.

I've been there too, most notably with an old NCR about the size of a full
tower case and around 150 pounds. It had 4 big 6 cell gel cells in it that
at the price of them, got replaced with 4 ea 14AH motorcycle batteries all
rigged so the overflow tubes dumped into a pint of soda. But it, even after
I lowered the float voltage by 4 volts, still boiled them dry at yearly
intervals. But it also ran this place for over 4 hours one night before I
got nervous and did a gracefull shutdown. We were 3 days getting power
restored that time. So after 3 years & 2 sets of batteries it got retired,
and when the 1500 kva belkin I bought to replace it went tits up after the
third battery in 3 years, refusing to handle a reset all the machines
brownout for teh 4th time, it got replaced with yet another belkin, but when
this ones gone, the next one will say APC on it, they care about linux.

It won't be that long either, I'm convinced that belkin engineers a minimum
operating temperature for their gel cells of something in the 170 degree
range just so they can sell a new battery set at $130 a year. I have to open
them up, and leave then sit and cool for about half an hour just so they can
be handled with bare hands. Grrrr. Good business model for belkin as long
as they can get away with it though. :(
