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 at 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/upsstats.cgi?host=tripplite@127.0.0.1:3493' 
| 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;-)
