How can I fix my UPS repeatedly disconnecting and reconnecting?

Question

I'm running a nut server connected to a Tripp Lite SMART1500LCD by USB. The device is behaving unexpectedly and I can see these kernel messages:

user@host:~ $ dmesg -T

You can see the device number increments each time the UPS reconnects.

I have replaced the USB cable and tried different USB ports but that did not affect anything.

Also, I can see this error every 22s.

user@host:~ $ sudo systemctl status nut-driver
libusb_get_interrupt: error submitting URB: No such device

The driver config:

# /etc/nut/ups.conf

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

If I manually run the driver this is the output with the UPS power summary removed:

What is causing the UPS to keep disconnecting?

If you shut down nut, will UPS keep disconnecting and reconnecting? — Nikita Kipriyanov, Dec 05 '19 at 06:08
After shutting down all nut services I'm still getting USB disconnects — Layne, Dec 06 '19 at 00:59
Then it is probably faulty USB port on the computer or faulty UPS. Try another port on the computer. — Nikita Kipriyanov, Dec 06 '19 at 05:51
All USB ports cause this issue. Also added another error probably associated with this issue. — Layne, Dec 06 '19 at 20:48
Then unfortunately it seems you have faulty UPS. Replace it. — Nikita Kipriyanov, Dec 09 '19 at 08:21

Inspired by this post, the solution for me so far has been to create a new udev rule:

# /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"

And change the pollinterval in my ups.conf:

# /etc/nut/ups.conf

pollinterval = 1

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

So far, 24 hours in, there have been no USB disconnects nor UPS stale data warnings.

There may be more graceful solutions out there but this works for now.

Your answer here work for my situation, a Debian 10 workstation with an Eaton Pro 1000 UPS. I edited my `/etc/udev/rules.d/62-nut-usbups.rules` to add the RUN commands `RUN+="/sbin/upsdrvctl stop; /sbin/upsdrvctl start"` to the end of the Eaton lines that already existed. Then added in `ups.conf`: `pollinternval = 1`. After manually disconnecting and reconnecting the UPS, I believe it is stable. – ender.qa May 28 '20 at 16:22

I also had this problem and I tried setting the pollinterval. It didn't help. But using the -DDDDDDDD argument and looking at the code, I determined that the problem might be the interrupts.

Try adding pollonly = "enabled" to your config in /etc/nut/ups.conf (possibly the file is elsewhere on your system). I did this and took out the pollinterval and, whereas I used to have a hang within an hour, now I've been going for a couple hours with a problem.

How can I fix my UPS repeatedly disconnecting and reconnecting?
