I'm still catching up on mail, so apologies if this was covered on a
more recent GitHub issue, but Tripp Lite PID 3016 is extra-sensitive
to certain combinations of USB cables and newer motherboards. If you
take NUT and XFCE power manager out of the equation, but the UPS still
generates a lot of disconnect/timeout/reconnect traffic in the kernel
logs, you might be up against this issue.
