Nut upsuser - Feb 2021 - [EXTERNAL] Tripp Lite "Remote Shutdown" when USB cable is attached

I wish I could provide more input but I'm unable to take the UPS out of
service for troubleshooting.  I have a few other models of TrippLite UPSs in
service but the SU3000XLCD is the only one that's shut down like this for
me.  I did contact TrippLite at the time and they asked me to call with the
computer and UPS available.  As that wasn't an option I didn't continue
down that path.  I don't think I've rebooted that Pi very many times if
at all so can't comment on whether that causes shutdowns.  At 4+ years I
suppose my setup is also aging out of relevance as well.

I am glad to see this is not just me having such problems.  I want to find the
root cause for all of those who suffer this bug.  If I have the USB cable
plugged in while the systems boot, it's a 50/50 chance of working, or power
cycling.  If it does work, then I live in fear of the next reboot!

Do you know any of the other models? Would be an interesting data point

I was on the tech support team back then... maybe we've come full circle.
I plan to dig into this sometime this week when I am in the office.

Thank you,
