[Nut-upsuser] Trouble getting Roline/Powercom UPS recognized

[Patrick M. Hausen]

Hi all,

I’m new to NUT and have some trouble getting my new UPS to work.
Since the HCL listed Powercom UHID models as „green“ I thought buying
a Roline (German rebranded Powercom) model would be a good idea.

The OS is FreeBSD:

FreeBSD freenas-pmh.local 11.2-STABLE FreeBSD 11.2-STABLE #0 r325575+6aad246318c(HEAD): Mon Jun 24 17:25:47 UTC 2019     root at nemesis:/freenas-releng/freenas/_BE/objs/freenas-releng/freenas/_BE/os/sys/FreeNAS.amd64  amd64

This is the device:

ugen0.6: <POWERCOM Co.,LTD HID UPS Battery> at usbus0
uhid0 on uhub0
uhid0: <POWERCOM Co.,LTD HID UPS Battery, class 0/0, rev 1.10/0.02, addr 5> on usbus0

This is the driver version:

root at freenas-pmh[~]#  /usr/local/libexec/nut/usbhid-ups -V
Network UPS Tools - Generic HID driver 0.41 (2.7.4)
USB communication driver 0.33

Came bundled with the FreeNAS installation.

ups.conf:

root at freenas-pmh[~]# cat /usr/local/etc/nut/ups.conf 
[roline]
    driver = usbhid-ups
    port = /dev/uhid0
    desc = “"

Debug output:

root at freenas-pmh[~]#  /usr/local/libexec/nut/usbhid-ups -DD -a roline
Network UPS Tools - Generic HID driver 0.41 (2.7.4)
USB communication driver 0.33

I’m a bit puzzled by the fact that it probes all ugen devices when the
device to use (uhid0) is explicitly configured …

Any help greatly appreciated.

Thanks,
Patrick
