I have one of those SMART1500LCDT which become unresponsive on USB once 
in a while. It looks like lsusb still finds the UPS in my case. My 
solution was an USB hub which can power down different ports via 
software control from the host;-)

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 -b 001 -d $(lsusb | awk '/0409:0058/ { print substr($4, 0, 
length($4) - 1); }') -P 1"
         /root/bin/hub-ctrl -b 001 -d $(lsusb | awk '/0409:0058/ { print 
substr($4, 0, length($4) - 1); }') -P 1 -p 0
         sleep 5
         /root/bin/hub-ctrl -b 001 -d $(lsusb | awk '/0409:0058/ { print 
substr($4, 0, length($4) - 1); }') -P 1 -p 1
         sleep 30
     else
         sleep 300
     fi
done
