I have a FLIR Lepoton camera module connected to my Raspberry Pi 3B+ board. Although I'm able to start it using this program (Lepton Module - Raspberry Pi video), when I'm trying to run another program which uses the numbers 0 or 1 as params for the onboard or USB camera, I got an error that the camera is not found, saying
Cannot identify device '/dev/video1
Any idea how could I find where is it actually connected?
