How to Config Octopi for RaspiCam and USB Camera

Hello, I have now tried many instructions but there are always other solutions. Octopi.txt additional config file and changes haproxy etc. i am confused...

I have octoprint version 1.10.2 and octopi version 1.0.0, old camera stack.

The first camera is a Raspicam and the second is a USB UVC endoscope camera.

What do I have to do now so that I can see both cameras? Do I still need the multicam plugin?
Can someone explain step by step how to set this up?

Im also wondering about this, ive been trying to get the pi cam working with a usb cam for a few hours. So bump!

Might this be of some help?
