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

David,
To answer your question:  In addition to the SU3000XLCD which shut down when I
connected my Raspbian Pi via USB I have a couple SU1000XLa, a couple
SU1000RTXL2Ua, and one SU3000RTXLCD3U connected by USB Raspberry Pi.  No network
or EPO connections.  I've only experienced the shutdown issue once on that
one UPS.

I also have several SU1000RT2U one SU2200RT2U which I monitor with NUT but they
predate USB so are connected by RS232.  At nearly 20 years old they probably
don't enter into this discussion but they have been working great with NUT.

>> 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.
Do you know any of the other models? Would be an interesting data point
>>  I did contact TrippLite at the time and they asked me to call with the
computer and UPS available.
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,
David Zomaya

I rebooted, and this struck again.  I can add just a little more info.  The
"REMOTE SHUTDOWN" happens within 2 second of the kernel loading. 
Before
init starts.  I tried a couple of times to plug in the UPS (USB), all after
the server was up and running.  Each time the UPS did a remote shutdown.

Any other ideas?
