Camera model
Logitech C270 and WinBook UVC CAM
What is the problem?
Cannot setup a second instance of webcam daemon.
What did you already try to solve it?
I had it working by following this guide: https://www.makersmashup.com/post/outside-the-box-multiple-webcam-setup-with-octoprint
I had to redo everything and it seems now the structure has changed, the guide is no longer valid.
Logs (/var/log/webcamd.log, syslog, dmesg, ... no logs, no support)
Additional information about your setup (OctoPrint version, OctoPi version, ...)
Pi 4, latest octopi .17.0
This is what I get when i start my second instance:

Also, when i list devices

/dev/video1
USB2.0 HD UVC AF Camera: USB2.0 (usb-0000:01:00.0-1.2):

I don't understand why each one has two identifiers. It wasn't like this on my previous setup. Also not sure what the top 3 are.
Any help appreciated, thanks.
