Two Webcams for Two Printers, 1 R-Pi..?

Camera model
Stylustar (cheap Chinese)
What is the problem?
Difficulty loading streams. I got one cam to work, but it was for the wrong printer. Disconnected and retried, and now no cams. "Stream loading....." For clarity, I am not attempting to run both printers/webcams at the same time, just plugged into the same Pi. I need the right cam to work for the right printer when it's connected.
What did you already try to solve it?
Have repeated connections, checked basic settings. (total Linux n00b, needs handholding)
Logs (/var/log/webcamd.log, syslog, dmesg, ... no logs, no support)
Just have "Webcam Stream Loading...." doesn't matter which printer I connect to in Octoprint. (both Anet A8's)
Additional information about your setup (OctoPrint version, OctoPi version, ...)
I will try another reboot when my current print is finished, but I was hoping for insight as to whether I can sort out how to get them working again (and how to tell Octoprint which cam is for which printer). That's the biggest issue. Thanks!

Please upload the /var/log/webcamd.log - also which pi is it?

I suggest you use WinSCP to download that file

username pi / pw raspberry
