I also operate an HP T1500 G3 which it's an Eaton made UPS. Connected on usb i get frequent communication errors and data aquisition stopped. Mine has a serial connection, also. Operating via serial has no trouble. Maybe it's something related to usb setting in bios, i.e. Legacy mode, speed setting, etc. However on serial mode looks like the eaton or hoe power protector software does not record any statistics...

Your problem with USB could be related to issue https://github.com/networkupstools/nut/issues/542 and should be fixed in the actual code, but we use network (netxml-ups or snmp-ups) and also have "data stale" errors. I hoped that someone could clarify if the USB issue mentioned is also lurking in the network drivers. Regards Andreas

Can someone comment what is the recommended way to monitor a Eaton UPS with nut? snmp-ups,netxml-ups or something other? Regards Andreas

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).

I would also suggest this is the same issue. Have you contacted the developer which has commented the issue? Regards Andreas
