V3.50~20 : Orion XS not showing in the Device List

Has anyone come across this challenge?

Orion XS is not showing in the Device list, however when I press the Firmware update button, system recognises that it is connected.

I have seen the Orion XS in the Device list on current setup before but not reliably on v3.41.
If I connect an MPPT with the same cable, it shows up reliably.

Orion XS on v1.05
Generic Venus Device (rpi or other) now on v3.50~20

Any guidance would be greatly appreciated.
