Nut upsuser - Jan 2023 - Problem with Multiple USB UPSs, including multiple apparent CyberPower

Actually in merged PRs of recent weeks there can be several suitable fixes:

1) support for common USB matching parameters in more drivers (though
usbhid-ups has long had it);

2) nut-scanner should provide more of these parameters in generated config
sections, in particular "device" port numbers;

3) for obscenely poor cases when devices can not be identified as unique,
new "allow_duplicates" flag was added, to not stop iterating if a
first
"good match" is busy. Caveat emptor here!

In your case, I hope adding the device numbers (3 digits) to configs should
help. Also `-x` is for command-libe specification of such parameters. In
config file it is just key=value. For these matchers they are generally
regexes (not shell globs). Please do RTFM :)

Thank you both for answering.

I tried with and without the "-x" as the manual wasn't clear
enough to me.
I tried with and without wildcards (e.g., "*SL*", "*SL
Series*", "SL
Series" for that one).
I tried other permutations before asking for help here.
("model" throws an error, "-x model" doesn't, which was
confusing)

I am not in position to change versions now - I am using whatever is
installed by Bullseye/Raspbian. (I wouldn't know how to ask the package
version be updated?)

If I unplug them and switch the order I plug them in (regardless of USB
slot?), it impacts which Cyber Power shows up by default - only the last
will be detected.
