using 2 webcams

[goldwingnut]

Been using OBS for about a month now with one Logitech C920 camera. I purchase a second C920 today with hopes of having two available cameras during a broadcast. I can get one camera to work but not a second. The first camera works fine. The second camera shows only a black screen, but the camera status light in one indicating it is active.
if I unplug either camera and then select the remaining it will work fine. When I plug the second camera in a second instance of the webcam appears on the source list and can be selected, once again a black screen and both cameras showing active based on the blue led on the camera.
I can make either camera work but not both.
Similarly, I had an old Microsoft Vx-5000 webcam that I tried with the same results.

What am I missing to make OBS work with two webcams of the same model?

I was using a Sony ZV-E10 as a second camera without issue for several broadcasts but it had a little to much lens so I decided to go with another C920. But no luck.
I'm using a 3 month old Studio M2Ultra 76-core/192G/8T

How are you connecting them to your computer? By usb hub? Is the hub powered? Individual ports?

One is though a powered hub (the first one that I've been using for a while) and the 2nd directly into the back of the Mac Studio. Both work, just not at the same time.

And if you connect both directly to the back of the mac studio instead of through a hub?

Tried that, same results,

Tried that, same results,

Not gonna lie, I have not tried two of the same cameras, but I don't think that should be an issue. Two of the Logitech cameras I have used will both fail when attached to a powered USB hub. My non-powered hub is USB C to the laptop and 4 port USB B, and the cameras have a USB C to USB B adapter. Non-powered hubs work fine; powered hubs, no go. After you attach the cameras, are you restarting OBS? Have you tried restarting the computer with the two camera's attached? (Just grasping for some ideas.) I have had an instance where OBS would not recognize the camera. I fired up Zoom, had them work there, closed Zoom, opened OBS, and it decided to like them. Go figure.

I did that for a while, both of them were recognized by obs with the same name, the problem came when I turned one off or on, the best thing would be to have two independent scenes for each camera, where the camera is always active and that scene is activated or deactivated from your main scene. or you can use came rename https://obsproject.com/forum/resources/camrename.1408/

Thanks for the info. Tried it on my windows PC and camremane worked. The Mac Studio once again has disappointed me, I guess I should not have believed all the hype about the Macs being so great at everything, it's not, it has its holes, the biggest one so far has been the one in my wallet. I should have seen the Kool-Aid stains on the faces of the Apple zombie. Foolish me.
After much research, the problem is not the webcam or OBS, but the MacOS, solution, taking the new webcam back to Best Buy and buying a different model. Seriously? My brand new $9000 Mac Studio is brought to its knees by having 2 of the same model webcams? If this was my first minor issue that caused the Mac ecosystem to stumble I would not consider it, but it's not, I have begun to have my doubts about my investment in transitioning to the platform.
