What is the problem?
Since fresh Octopi flash/install eyecam will not start properly
What did you already try to solve it?
Lots and lots of various configurations in /boot/OctoPi.txt
I also tried giving it " /dev/v4l/by-id/" (with my gnarly actual USB name "usb-OmniVision_Technologies__Inc._USB_Camera-B4.09.24.1-video-index0")
as shown in this very helpful post with it still not working
Logs (/var/log/webcamd.log, syslog, dmesg, ... no logs, no support)

- It seems that you don't have VL805 (Raspberry Pi 4).
There should be no problems with USB (a.k.a. select() timeout)

see it? the damn space prior to the options killed it
I found that if you go to the 8080 url you get the mjpeg stream site, it then gives you the stream url
mine showed a url of http://192.168.1.136:8080/?action=stream
so I went into the octoprint options for classic webcam and changed the stream to above and then everythng worked.
