Using Blackmagic Intensity Shuttle USB 3.0 in Max in 2021?

Hi folks!

I am trying to use a Blackmagic Intensity Shuttle USB 3.0 in Max and I believe I tried every combination, but I just can't get it to work. It works in OBS so not a problem with the drivers or anything like that.

In Max I tried using it with [jit.grab]. I tried all these below with all possible format combinations.

Blackmagic WDM Capture (7)
Decklink Video Capture
Intensity Shuttle [Native]

I also have these of course:

Chicony USB 2.0 Camera
OBS Virtual Camera

I also tried sending a format -1 message. It reports jit.grab: Blackmagic device - searching for valid video input format and nothing else.

In the Desktop Video Setup app I set the Intensity Shuttle video output to 1080i50. Should I set it to something else?

Any other ideas?
Thank you so much!

PS: If I unplug the capture card, I only get :

vdevlist
Chicony USB 2.0 Camera
Decklink Video Capture
OBS Virtual Camera
