[Nut-upsuser] Question on EATON UPS

Fri Mar 24 17:46:43 GMT 2023

Hi Jim,

I have 2 drivers which have launched well connecting 2 APC UPS (both with usbhid-ups)

They have both bus & serial set.

The Eaton is the third one. I have removed serial and bus from the configuration.

                driver : usbhid-ups

                port = auto

                vendorid = 0463

                productid = ffff

                pollonly

I have highlighted the errors while launching the driver:

The "unknown" fields mean the driver did not get that piece of information from libusb. In case of Manufacturer/Product which are unknown in the later post, but known in the first, I suppose you had another driver running, or the kernel still owned it (udev misbehavior, not handing it off after reconnections, etc.) and so exclusive access was not given to the new (currently reporting) process.

The "Device" matching specifically had a problem fixed in the master branch a few months ago. You can try to comment it away from your ups.conf for a quick workaround, and match by remaining fields (assuming their values are correct).

Hope this helps,

Jim Klimov

The UPS has been defined in ups.conf as:

[myups3]

driver : usbhid-ups

port = auto

vendorid = 0463

productid = ffff

desc = "5S"

bus = 002

device = 014 

pollonly

I have only:

[ups02]
driver=usbhid-ups
port=auto

serial = [redacted]

I have an Eaton 5P750 connected via USB and agree, a less specific entry in ups.conf works fine for me:

[ups]

        driver = usbhid-ups

        port = auto

        vendorid = 0463
