Have to RESTART WEBCAMD to get video feed

Just installed a second webcam and got both services running but now just a few random things that i cant seem to figure out....

What is the problem?

  1. If only first camera (called on by webcamd) is plugged in, it will start automatically BUT if both ARE plugged in, it does not. (second camera called on by webcam2d)

  2. Second camera will not startup on boot automatically

What did you already try to solve it?

  1. use the command sudo service webcamd restart in putty to enable camera1
  2. launch the file by typing /root/bin/webcam2d to enable camera2

BOTH work until i close putty or restart.

I'm having a similar problem. I have 2 cameras: a RasPiCam and a Logitech C615. When I start up my RPi, I can see the power-on light for the Logitech USB camera come on initially, but then it goes off, but the associated webcam service is still running:

When I go to the web address for the camera, I get a black screen. If I restart the service, it works fine until I reboot. Restarting Octoprint has no effect.
