Used to work fine, but now OBS only alternates one cam to another, but i need both to show up.

I am not sure what could've caused this. Either installing DaVinci Resolve, or StreamFog. I had uninstalled StreamFog, but there may be some issues clinging on from then that causes my OBS to act like this.

I have tried a few things:
- restarting
- changing resolution
- deactivate when not in use
- plugging USB into different sides
- using a USB hub for one of the cams
- switching the hub USB to a different USB port on my laptop, etc.
- both my cameras are alive within device manager
- I can switch one to another but only if i deactivate the working one, move to the not working one, and de-activate and activate it to reset.

I have been using this set-up of two cameras on OBS for years. The only new thing that happened is StreamFog (which I have uninstalled) and DaVinci Resolve. But both of them have nothing to do with USB...

I need both to work at the same time. If anyone has any suggestions for me to try, I'll give it a go. Thanks!

Everywhere it says not enough USB power. I have unplugged Streamdeck as well, and no new USB's are in my powered USB port.

I think, it was without the

20:51:11.399:     - source: 'Nvidia Broadcast' (dshow_input)

OBS has own filters to remove background from the camera. Why do you need this Nvidia Broadcast virtual device source when running OBS? Do you find OBS filters too bad (not handy, buggy, resource demanding) or what?

Anyway, to troubleshoot the problem it is better to make a new Scene Collection in OBS with minimal set of sources. Just two cameras. And then switch between them. This may give you a clue what is wrong in your setup.
