Can not get second usb cam to start automatically also Video0 shows up Video1 says it does not exist

Can not get second usb cam to start automatically also Video0 shows up Video1 says it does not exist
I can manually start the usb cam by typing
cd ~/mjpg-streamer
./mjpg_streamer -i "./input_raspicam.so -fps 10" -o "./output_http.so -p 8081"&

Is there somewhere i can put the mjpg streamer command so it starts the usb cam on boot?

This might help...

already tried every 2 cam setup online that could be found under google.

those instructions talk about scripts that do not exist in the octopi image

example webcamDaemon does not exist in /home/pi/scripts/
