      Also its not showing a name of the camera as a device, but I know its the 32e4: since it goes away when I unplug it

        maybe motion is keeping the camera busy if you've already tried installing that?

        Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

          I only installed motion, not sure what else would be keeping it busy.

            I am using motion on Pi but with the Pi camera - so things may be a bit different but ....

            Can I suggest that you

            1. unplug the usb camera

            2. make sure motion is off
              sudo systemctl stop motion

            3. plug the usb camera back in and see if it is "seen" by the OS (I assume you are using debian buster ?) using one or a combination of
              lsusb
              dmesg | grep -i usb
              ls /dev

            4. assuming that the usb camera is "seen" and shows up as /dev/video0 - check that the motion config file /etc/motion/motion.config has a line with videodevice /dev/video0

            5. If all is well - restart motion
              sudo systemctl start motion

            If this is instructions on how to "suck eggs" please disregard.

              My dev folder has many video lines.. video0 through video16

              So now I think my camera is actually video1. It seems happier on the log. How can I tell what the URL will be for the camera stream to work with DWC? I understand it has to be an image sequence. Do I need to set the url in the motion.conf properly for that? Can someone give me an example?

              thanks again everyone

              Jason

                The URL should be the IP of the Pi with the port you've configured.

                  The port is set in /etc/motion/motion.conf

                  I cannot remember the default (8080? 8081?). Look for the line like this

                  # The port number for the live stream.
stream_port 8081

                  You can then access it with http://[IP]:8081 (in the example above)

                    Yes, I did both of those things, but i cant get it to work on both the local pi screen and the web page on another pc, either local port or remote, it seems like it has to be one or another. there is an option in the motion setup "stream_localhost" has to be on for it to work locally on attached PI screen and has to be off to work on a remote web browser. How do i make it work on both at the same time? Also the update rate seems to be about 1hz or worse.

                      I have

                      stream_localhost off

                      and use a browser to connect. You can use the browser on the Pi to do the same thing (but not sure what the utility is there).

                      Frame rate is set in the motion.conf (15fps default from memory) but this is not the browser refresh rate (closer to 1 per sec). I have not tried to set-up for full real-time streaming since the bandwidth required would be quite high.

                        Stuartofmt, thank you. So you get an image on both a local PI screen and another pc browsing in? What URL did you provide to the DWC configuration?
