OBS does not register camera until restarted

[richard.prince@manchester]

Hi,
This might be something really obvious, but OBS (Windows 10) does not recognise my Logitech Brio when first launched. It seems to be doing something to the camera, because the "on" led lights up. However, no capture appears. If I immediately quit and then restart OBS, it finds the camera and captures from it. It is behaving almost like the camera is being used by another program, but it happens when OBS is the only active application. Any ideas would be gratefully listened to!
Here is the URL of the log file. The camera in question is the New Brio

Thanks

Hi Thanks for the link to the programme. I have the Brio and a Focusrite Scarlett audio interface as my only two USB 3 devices. I moved them to different root hubs, but it didn't make a difference. It is like a toggle switch. I start OBS, quit and restart it, and everything is fine. Next time I start it, I have to quit and then restart. It is a pain, but at the end of the day I can still do what I need!

You have the Brio added as two separate Video Capture Device sources, "Brio Camera" and "New Brio".
Each VCD source counts as a separate 'program'.

You need to delete one of these entirely, from every scene in which they exist, ALL of them, and 'Add Existing' instead of 'Add New' to re-use the camera properly.

If you need to apply different Filters to different instances of the camera (as it appears you are doing), add the camera to a Group in each scene and apply those filters to the Group instead, not the VCD itself.
