FYI: Just in case it proves to be related, I logged a similarly sounding issue recently as https://github.com/networkupstools/nut/issues/651 (or 661?) - my guess is maybe somewhere a rounding delta got truncated in the maths, causing a quick flop of data stale and unstale verdicts. Also FYI, I had some connectivity issues with an USB UPS using libusb-0.1 which were resolved by switching to 1.0 or 1.0-0.1-compat. I think the PR for that is still open in upstream NUT, so it is not quite in master - but should be easily applicable (and of course one should build/package it from source).
