I'm still sort of new, but: Build nut from source and use that (the tip of master from it), rather than whatever old code your OS provides. 2.7.4 is ancient and there have been a ton of improvements since then. I am not sure there is anybody interested in helping you work on 2.7.4. Run the driver with debugging flags to get verbose logging. upsc shows that variables you expect aren't there, and verbose logging will give you some insight into what's happening. See if other code, perhaps proprietary and even Windows, if you can hold your nose and suspend your free software ethics :-), will report anything more. Find the docs that show what is available via HID and read the driver code to see if anything is missing. My guess is that your problem is one of: something is going wrong and the device just isn't getting read. The HID data structures do not line up between what nut expects and the device provides and that upgrading to current nut is reasonably likely to avoid a lot of issues, even if it doesn't immediately work. But it might. _______________________________________________ Nut-upsuser mailing list Nut-upsuser@alioth-lists.debian.net https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser
