No Video Device Detected - Intensity Shuttle

Hi there,

I have uninstalled/reinstalled Desktop Video Setup, restarted my computer several times, made the necessary adjustments in the privacy/security section of my system preferences (Mac OS Big Sur 11.1) and my Macbook Pro supports USB 3.0, but I'm still getting "No Desktop Video Device Detected."

I have emailed BlackMagic and called them during operating hours, but it goes straight to voicemail...

Any help here would be greatly appreciated. Thank you.

I have the same problem. I couldn’t broadcast my church service today because of this!!
Any help with this would be greatly appreciated.

Same condition with my Intensity Shuttle USB 3.0. Same day - Sunday.

intensity shuttle USB 3.0 should no longer supported

Is that an official statement ? Intensity Shuttle - USB3 not supported on Big Sur ? can't imagine that for a USB3 device... BMD could update drivers for that, is my guess.
I use the Intensity Shuttle - TB2 on 2 MBP's one with Sierra OS and one with Catalina OS works fine for me sofar...
