You may need to check my configuration (done from GUI)

from server i can contact the specified port :

-rwxrwxr-- 1 root wheel 6B Sep 1 10:45 upsmon.pidThe chown command doesn't touch/changes the files IN the /var/db/nut/ folder, the ones you've shown.
It changes the owner of the nut folder, see my example above. -
@Gertjan right
so i need to change the file's permission within the /var/db/nut directory ?
like :
chown -R nut:nut /var/db/nut/?
EDIT: maybe reinstalling the package can restore the initial permissions ?
i think i restored the correct permissions on the directory as foolows :
ls -lah /var/db/nut/ total 9 drwxrwx--- 2 nut nut 128B Sep 1 11:15 . drwxr-xr-x 9 root wheel 832B Sep 1 02:55 .. -rw-r--r-- 1 root nut 6B Sep 1 10:45 upsd.pid -rw-r--r-- 1 root uucp 6B Sep 1 10:45 upsmon.pid -

That's a good news.
but unfortuntely i still can't roperly start the driver./usr/local/libexec/nut/usbhid-ups -a ups -DDNetwork UPS Tools - Generic HID driver 0.47 (2.8.0) USB communication driver (libusb 1.0) 0.43 0.000000 [D3] main_arg: var='driver' val='usbhid-ups' 0.000030 [D3] main_arg: var='port' val='auto' 0.000051 [D5] send_to_all: SETINFO driver.parameter.port "auto" 0.000077 [D1] debug level is '5' 0.000672 [D5] send_to_all: SETINFO device.type "ups" 0.000691 [D2] Initializing an USB-connected UPS with library libusb-1.0.0 (API: 0x1000102) (NUT subdriver name='USB communication driver (libusb 1.0)' ver='0.43') 0.000699 [D1] upsdrv_initups (non-SHUT)... 0.000961 [D2] libusb1: No appropriate HID device found 0.000975 libusb1: Could not open any HID devices: no USB buses found 0.000981 No matching HID UPS foundit may be related with the /etc/devfs.conf /etc/devfs.rules.
I think i should reboot the pfsense as mentionned in troubleshooting here :
https://blog.victormendonca.com/2020/10/28/how-to-setup-ups-on-pfsense/
but as it is in production i need to wait .
I'll try to tweak the devfs rules/conf .

'nut' is the owner when installed
Look at line 57 in nut.inc.
It's one of the things I need to fix in the transition from using a release version of nut to using the development version of nut.
I won't be able to get to it until end of next week.

Should not be needed.
Can you run the following:
- disable the UPS service and save
- unplug the usb connection and wait a few seconds
- re-plug the usb connection
- run "usbconfig -v" in a shell
- re-enable the UPS service and save
- run the usbconfig command again
And post the results please?

Thank you it worked !
I changed the usb cable in case it was malfunctioning.
I also changed the usb port : from ugen1.3 to ugen0.6at some point i needed to chown back the /var/db/nut directory to nut:nut with
chown -R nut:nut: /var/db/nut/here is the output of usbconfig -v :

So i'm monitoring the service in case anything goes wrong.
Do you think i may need to tweak the driver's conf with some of this option :
for example :
waitbeforereconnect=30i'll keep this post open so i can confirm it works flawlessly next week after another reboot.
Thank you very much for help.

@abs0new Unfortunately, the issue of ownership of /var/db/nut will currently arise every time you reboot.
To remediate, you can either edit nut.inc, add a boot time shell script, or wait until I can fix the package.
