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.
