So, what is your conclusion?

IFAIK, both iPolar and IGuider do work under ASCOM.
iPolar works under INDI. iGuider doesn't work under INDI.

My CEM40G doesn't have USB3 hub. Only USB2.
iPolar and iGuider connect to it internally.
There's one USB external input which works.

INDI/Ekos do recognize both cameras but iGuider doesn't work properly.
iPolar works.

My two cents.
