[Nut-upsuser] NUT can't connect to USB UPS on OpenBSD
Hi everyone,
I have a problem trying to configure NUT with a Eaton 5S1500LCD on
OpenBSD. It is listed as supported
(https://networkupstools.org/ddl/Eaton/5S1500LCD.html) with the driver
`usbhid-ups`, from at least version 2.6.4 and upward.
The OpenBSD that I have is 7.1. I installed NUT via `pkg_add nut` and
it installed version 2.8.0. No matter what I do, I can't seem to make
NUT see the attached UPS via USB.
What follows (between the pound signs) is some debug info on my setup
of OpenBSD and NUT. The symbol ? is the command prompt and I sometime
add some explanation as comments above the prompt.

I don't know why the driver requires the `root` user, I thought I had
configured the `_ups` properly everywhere. But even with `root`, it
can't start. That's pretty much all I can think of on how to debug the
thing. I just don't know what is missing in all the stuff I listed.
Any help would be appreciated, thanks,

[Nut-upsuser] NUT can't connect to USB UPS on OpenBSD

We have some devd information here: https://github.com/networkupstools/nut/tree/master/scripts/devd https://github.com/networkupstools/nut/blob/master/tools/nut-usbinfo.pl#L181-L196 also implies that on FreeBSD, `chmod g+rw` is needed on the appropriate device node. If that fails, I'd recommend using ktrace to find out what is failing, such that you get the "no USB buses found" error.> _______________________________________________ > Nut-upsuser mailing list > Nut-upsuser at alioth-lists.debian.net > https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser
