BlackMagic ATEM Mini device not recognized

[kermed]

Hello,
MacBook Pro running BigSur 11.7.10
ATEM Software 9.3.2
OBS 30.0.2

I use OBS to stream to Youtube, from a BMD ATEM Mini. I've used this setup as is for almost 2 years. Last time I used it 2 days ago everything worked fine (using a few versions back of OBS and ATEM Software). Today, I could not get OBS to capture the output. Just a black screen, although I did have audio. I've tried multiple things, deleting the source in OBS and trying to recreate it, making sure no other application is using the source, etc... When I try to add the source back in OBS, and select Black Magic Device, in the next window that pops up where you normally would select the BMD device, the field label is red in color and when you try to select the device from the list, there is nothing listed except for a checkmark. I'm at a loss as I've been at this for hours. I have tried a new USB cable between the ATEM and MacBook, which didn't change anything. I've updated OBS and ATEM to the latest versions and still experiencing the same issue.

Just out of interest, is the USB port blocked/restricted? It similar to what I experienced when I try to use my work laptop and this happens because of USB restriction.

I am having same issue.
I was playing around with UsbTreeView.exe and USBDeview.exe
later on my Atem Mini Pro no longer shows up on my OBS nor on my base Windows 11 OS.
I remember clicking "Disable + Enable Selected Devices on my Atem Mini Pro and Blackmagic..

I have tried the followings below and none of them worked out for me..

* Power Cycle Atem Mini Pro
* Reboot my Windows 11 machine
* downloaded and installed - latest 27 Aug 2024 ATEM Switchers 9.6.1 Update
* unplugging/replugging USB C cables on both end of Atem Mini Pro and Windows 11 PC
* tried changing to different usb 3.0 blue port
* upon inspection on Device Manager (with Show Hidden Devices Enabled) - blackmagic is no where to be found

Has anyone found a solution to this? I am having this issue as well.
I tried what the other users here have tried to no success.

For anyone who encounters this fringe issue. We ended up swapping it out for a Blackmagic Decklink Duo 2. It worked like a charm.
