We had that discussion about the SMART1500LCDT & USB a long time ago:-(
I bought mine in 2013 (still going strong on the second set of
batteries) and in August 2016 we had some discussions about the USB
disconnects.
I now use an USB hub which can turn it's ports off via software commands
and when my Linux box (Odroid X2 - ARM) looses the connection, it
basically cycles the USB port of the UPS and then it can connect again.
root@odroid-www:~/bin# cat check_ups.sh
#!/bin/bash
while true
do
x=$(curl -s -o -
'http://192.168.1.5:85/cgi-bin/nut/[email protected]:3493'
| sed 's:<[^>]*>::g' | awk 'BEGIN {s = 0; } $1 == "Status:" { s = 1;
next; } s == 1 { print $0; s = 0; }')
if [ "$x" != "ONLINE" ]
then
logger -p daemon.warning "Triplite is not offline, trying to
restart USB"
/root/bin/hub-ctrl -b 001 -d 005 -P 1 -p 0
sleep 5
/root/bin/hub-ctrl -b 001 -d 005 -P 1 -p 1
sleep 30
else
sleep 300
fi
done
Not sure, if this is still the same problem. But I have my solution;-)

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?
