I don't have a quick answer for you but I'll be in the office later this week and can grab a model with the same protocol and run a test on one of my Ubuntu boxes (which should be close enough to your Pi setup).


Thank you,
David Zomaya
Tripp Lite

I am kinda stuck on this one.  Whenever I attach (USB to a linux box) my TrippLite UPS, it "REMOTE SHUTDOWN".  This is a new problem that has cropped up in the last 6 months.  At first I thought it was a NUT configuration issue, but now I believe this  to be some kind of kernel bug?  When I plug in the UPS, I can see the system logs show the UPS, then everything powers off.


UPS LCD shows the below error when I plug in the USB cable:
"OUTPUT OFF"
"REMOTE SHUTDOWN"


I tested this against 2 different X86 boxes and a Raspberry Pi. All cause the same result in the UPS.  Only one box (nas) has NUT installed and configured.


UPS is a Tripp Lite SU3000RTXLCD2U.


I am totally stumped on this one.  Below is a dump of basically all my specs.  Any ideas?
