Nut upsuser - Dec 2019 - [EXTERNAL] Re: Tripp Lite SMART1500LCD repeatedly disconnecting and reconnecting

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

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?

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 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"
         /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;-)

Charles, thank you for that link to David's earlier message. I tried adding
those udev rules and changing the pollinterval. I need to do some tinkering
but I don't think the part RUN+="/sbin/upsdrvctl stop; /sbin/upsdrvctl
start" is working right. If I manually run the commands then the USB
disconnects stop and there are no kernel messages. Running "sudo
/lib/nut/usbhid-ups -DD -a ups" also looks clean to me. I'll be sure to
update if I figure out how to get it fully working. Thanks!

Thanks Marco, I may try this if I can't get David's udev rules to work.

Thought I'd follow up in case someone else runs into this issue. In the end
what worked for me was tweaking the udev rules. I have had no USB
disconnects or stale data warnings so far. I only used one rule for my UPS:

# /etc/udev/rules.d/62-nut-usbups.rules

SUBSYSTEM!="usb", GOTO="nut-usbups_rules_end"

# TrippLite
#  e.g. TrippLite SMART1500LCD - usbhid-ups
ACTION=="add|change", SUBSYSTEM=="usb|usb_device",
SUBSYSTEMS=="usb|usb_device", ATTR{idVendor}=="09ae",
ATTR{idProduct}=="2012", MODE="664", GROUP="nut",
RUN+="/sbin/upsdrvctl
stop; /sbin/upsdrvctl start"

LABEL="nut-usbups_rules_end"

My ups.conf:

# /etc/nut/ups.conf

pollinterval = 1

[ups]
driver = usbhid-ups
port = auto
desc = "Tripp Lite SMART1500LCD"
vendorid = 09ae
productid = 2012

And I also removed MTP as it was trying to take the device.

sudo apt-get remove --auto-remove libmtp-common
