Hello, i have 5 logitech c920 camera ,1 logitech c922 and 1 zoom camera. I want to use all of them to make a live stream, the problem is that all of them are detected by pc but when i add them in obs @video capture device only 4 logitech cameras are working and the zoom camera, 2 of them i see only a red point but i can open the propreties.
I tried on 2 laptops. and the same thing happens.
Any ideas why they don't work ?

I recently had this exact problem, turned out that I could only have a certain number of cameras connected to each group of USB ports. Try different combinations of USB ports.

How many cameras did you manage to make work?
