I have a HP PC running ubuntu 20.10 with OBS installed.
Connected via USB I have a Logitech Webcam, a Blue Yetti Microphone, Cheap action cam and a HDMI capture device. I also have a wireless keyboard and mouse combo but I think that’s out of scope.
When I start OBS it seems that I only get either the actioncam OR the HDMI capture but not both. When I open the video capture (v4L2) source and check the device dropdown I only see the Webcam and one of them. I am fairly sure that it only shows the most recently connected device (so unplugging and re-plugging makes it switch).
If I unplug and re-plug things then sometimes I do manage to get both working at the same time but more by luck than judgement I fear.
Does anyone have any idea what’s going on or suggestions for ways to start working this out? I guess a starting place might be something else that is capable of looking for and opening USB video input devices might be a start to rule out an OBS issue but I’m not really sure what to look for.
In case it helps any if I lsubs I get;

each time I unplug and replug the device 00x number goes up by 2 for the Generalplus actioncam and by 1 for the Sunplus (which is the HDMI Cap)
