[Nut-upsuser] PowerShield Defender 1200VA

[Walter HILL]

Hi,

Sometime ago I asked the question about getting nut to run on my iMac as
I was having trouble getting the USB driver to behave with OS X. The
same driver under LINUX is fine. It was suggested that the better option
might be to run nut on a Rasberry PI instead and monitor the nut daemon
from the iMac.

Well I have bought a Rasberry PI, I have other things planned for it. I
have installed nut 2.7.4-5. The blazer_usb driver detects the UPS so far
so good. What I have noticed though is that the kernel is continuously
(re)detecting the UPS on the USB port. I tried the USB attached to an
Ubuntu VM as I see the same issue.

I realise that this is a LINUX issue rather than a NUT issue but I was
hoping that someone using NUT may have experienced a similar issue with
a similar type of UPS.

raspberrypi (pi) /etc/udev/rules.d $ uname -a
Linux raspberrypi 4.14.98-v7+ #1200 SMP Tue Feb 12 20:27:48 GMT 2019
armv7l GNU/Linux

I have read suggestions about modifying UDEV rules and changing the USB
cable. I've tried another cable. The UDEV rule file that ships with NUT
appears to contain a record for this UPS

raspberrypi (pi) /etc/udev/rules.d $ grep "0665" 62-nut-usbups.rules
ATTR{idVendor}=="0665", ATTR{idProduct}=="5161", MODE="664", GROUP="nut"

Can anyone point me in the correct direction?

Thanks
