Yes I have one that *completely* dropped off. Nothing in lsusb. The unit 
worked intermittantly when first installed. Then the USB interface just 
disappeared even after power cycling the unit. I've been lazy about 
calling tech support.

This means no USB activity at all -- and not a bad USB cable or port -- correct?
If so, obviously probably not fixable on the software-side BUT I'd be
curious to know the serial number and if you have in fact narrowed it down to a
completely dead USB port on the UPS.


Thank you,
David Zomaya

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 at
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
