I have a TrippLite OMNI1500LCDT unit that I could not get to work properly using NUT running on FreeBSD on a new SuperMicro motherboard. I ran into similar USB issues. I eventually just gave up trying and switched over to CyberPower, which has been working fine for a couple of years. The TrippLite unit is now doing low priority work (i.e., the entertainment console in the living room). It is the last TrippLite UPS I'll buy. _______________________________________________ Nut-upsuser mailing list [email protected] https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser
