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.
