[Nut-upsuser] connection pb with blazer_usb with infusec UPS

[MATHIEU Clement]

Hello

i need your help regarding the following issue :

i have a hero touch ups from infosec. it is connected via USB to a raspberry pi 3.
i’ve configure ups.conf file as below

[HERO]
       driver = blazer_usb
       vendorid = 0665
       productid = 5161

either with
       port = auto
or 
       port = /dev/hidraw0
or
      port = /dev/ttySo
   
the connection never works

i get the following log from command line :
sudo /lib/nut/blazer_usb -a HERO -DDD -u root
