[Nut-upsuser] New User Questions - With Belkin USB

[David White]

Hello all and thanks. I read here 
<https://mn3m.info/posts/configure-ups-monitor-using-nut-on-debian/> 
while searching around for my issue's resolution. In this I see that 
this nut driver is creating and using an entry in /dev (in this case 
ttyS0). So I "ll tty*" and see nothing with nut. Since this is a USB 
UPS, I suppose I should be looking for something in /dev/ttyUSB*. I have 
a single entry there ttyUSB0 but that is created and used by me for 
running Heyu for my home automation system.

Any chance I am onto something here?

Thanks
