[Nut-upsuser] Apple iMac OS X 10.13.5 | Powershield Defender 1200 UPS

Hi All,

I am trying to install and configure NUT [ 2.7.4 ] to shutdown my iMac [
10.13.5 ] via my Powershield Defender 1200 UPS when the UPS reaches a
specified lower battery condition.

The Defender 1200 attaches to the iMac via USB.

The Defender appears on the the HCL - The required driver is 'blazer_usb'

The UPS is visible on the USB bus as:

        USB to Serial:

          Product ID: 0x5161
          Vendor ID: 0x0665
          Version: 0.02
          Speed: Up to 1.5 Mb/sec
          Manufacturer: INNO TECH
          Location ID: 0x14400000 / 25
          Current Available (mA): 500
          Current Required (mA): 100
          Extra Operating Current (mA): 0

I have placed an entry in ups.conf for the UPS.

I have created modified nut.conf MODE=standalone

I have also created upsmon.conf

If I run 'upsdrvctl start' as root I get:

h-3.2# ./upsdrvctl start
Network UPS Tools - UPS driver controller 2.7.4
Network UPS Tools - Megatec/Q1 protocol USB driver 0.12 (2.7.4)
Can't claim USB device [0665:5161]: Function not implemented
Driver failed to start (exit status=1)

I can see that the VendorID and ProductID appear correctly but the
driver fails to start.

I have tried searching for other people using the Defender 1200 with a
Mac ( in recent times ) but I appear to have 'struck out'.

Does anyone know of a relatively recent guide to getting this UPS
running on a newer version of OS X? I am aware that Apple have been
re-engineering their startup process so I expect that getting the driver
to work may be the least of my problems.
