No matching HID UPS found
Driver failed to start (exit status=1)

Config file

Code: [Select]

/usr/local/etc/nut/ups.conf

Code: [Select]

[APC]
driver=usbhid-ups
port=ugen0.3

I've set /etc/devfs.conf to

Code: [Select]

perm usb0 0770
own usb0 root:uucp

perm uhid0 0770
own uhid0 root:uucp

[nut_usb=10]
add path 'ugen0.3' group wheel user uucp mode 0770
add path 'usb/0.3.0' group wheel user uucp mode 0770

Reloaded rules with

Code: [Select]

/etc/rc.d/devfs restart
If I run from console

Code: [Select]

/usr/local/libexec/nut/usbhid-ups -u root -D -a APC it works

Code: [Select]

Network UPS Tools - Generic HID driver 0.41 (2.7.4)
USB communication driver 0.33
   0.000000     debug level is '1'
   0.000802     upsdrv_initups...
   0.066616     Using subdriver: APC HID 0.96
   0.066641     104 HID objects found
   0.068696     Path: UPS.PowerSummary.iProduct, Type: Feature, ReportID: 0x01, Offset: 0, Size: 8, Value: 1
....

If I run without root parameter

Code: [Select]

/usr/local/libexec/nut/usbhid-ups -D -a APC I get

Code: [Select]

Network UPS Tools - Generic HID driver 0.41 (2.7.4)
USB communication driver 0.33
   0.000000     debug level is '1'
   0.000828     upsdrv_initups...
   0.001004     No matching HID UPS found
So it seams to NUT USB permissions issue, I can't reboot right now after I edited /etc/devfs.conf but I reloaded devfs service

Please help!

I fixed

/etc/devfs.conf

Code: [Select]

perm    ugen0.3 0770
own     ugen0.3 uucp:wheel
/etc/devfs.rules

Code: [Select]

[nut_usb=10]
add path 'ugen0.3' group wheel user uucp mode 0770
/etc/rc.conf

Code: [Select]

devfs_system_ruleset="nut_usb"
Restart service to read new config

Code: [Select]

/etc/rc.d/devfs restart
Check permissions

Code: [Select]

ls -l /dev/ug*Output:

Code: [Select]

lrwxr-xr-x  1 root  wheel  9 Nov 18 11:53 /dev/ugen0.1 -> usb/0.1.0
lrwxr-xr-x  1 root  wheel  9 Nov 18 11:53 /dev/ugen0.2 -> usb/0.2.0
lrwxrwx---  1 uucp  wheel  9 Nov 18 11:53 /dev/ugen0.3 -> usb/0.3.0
lrwxr-xr-x  1 root  wheel  9 Nov 18 11:53 /dev/ugen0.4 -> usb/0.4.0
Now it should work!

Ditto. I just did this on a 22.7.11 after moving hardware and restoring backup.
