Hey! I’ve been trying my best to find a way to add two cameras to my printer, but no matter what I do, everything goes wrong.
I’m using a usb hub to connect my cameras to the only usb port. Here’s my latest crowsnest.conf and crowsnest.log below…

At the moment, I’m using legacy crowsnest but will update it once this post will be live. I have tried multiple cameras, usb hubs, power options for the usb hubs and device names for each camera. No matter what I do, only one camera is on each time I fix and reboot the printer. Nothing has helped me so far. I hope you can
It looks like there’s only one V4L device detected, so I think your first step needs to be making sure that both cameras are detected and working in Linux before trying to configure crowsnest to use them.
Just updated the config and now it looks like this. I also plugged in a new camera.
