I tried as much as I can to reduce the steps to get that done.

That is the device path I try to force for Raspicams.

**Q:** I use a Raspicam and a USB one but I cant get them both for unknown reason. How do I fix that?

To fix that please unplug the USB one and reboot.
Plug the USB Cam in, after the stream of the raspicam is shown.
After that use the `/dev/v4l/by-id/<whateveryourdeviceidis>-index0` for the USB one and restart crowsnest.
