I've been having a problem where my C270 will not working in obs. If I uninstall via device manager and redetect it will start working intermittently.

Sometimes when I shut down obs and relaunch it will work intermittently.

However, it works 100% in the Win10 camera app.

It's the only camera connected to my system that is having issues right now.

Have you installed the software that came with the camera? Some times you need to download it from the vendor site. In this case Logitech.

The camera software is installed. It's the only camera not working in OBS but works everywhere else in any other application.

I uninstalled it and selected to remove the drivers. I rebooted and it's using newer drivers now.

The video settings panel was an old style previous and now it's the newer Logitech video panel.

I removed the camera source from every scene since I only need it in one and re-created the source.

I selected the camera and it worked. Once I closed obs and relaunched the camera isn't working in obs but still is working everywhere else.

I might have fixed it, swapped the camera with another usb device and it seems to be working now. I did some reading and the error can be related to too many devices on the same bus.

Did some testing, closing relaunching the app, rebooting the system. It's working now, definitely was a bus issue.
