I haven't tried it on RaspberryPi, but if there's some specific Tripp Lite information I can help with, let me know.

My UPS is connected to a Raspberry Pi by USB. After a few hours of working, the service fails. Looking at kernel messages I noticed that the device is repeatedly disconnecting and reconnecting.
I have tried using a different USB port and using a brand new USB cable. I have not had success by changing config parameters like pollfreq/pollinterval/etc.
What is causing the UPS to keep disconnecting?
Not sure (it's a protocol issue lower than NUT), but does this post from Tripp Lite help the UPS automatically reconnect?
(you may need to do some RedHat-to-Debian translation for some of the pathnames.)
