USB AD2USB port weirdness

In my Serial Port configuration

I see two entries…

it seems that the second one is the one that I have to select for the Ademco Panel.

So, why is there two entries here? (latest firmware, VeraPlus).

Also, after a reboot, I sometimes have to go back in and reconnect the ‘Used by device’. Any idea why it doesn’t stick?
