Hi, There may be many LEDs on the webcams. One LED may be used for the streaming state, Some other ones may be used to give more light in dark rooms. One webcam, the microscope 093a:050f, has a top and a bottom lights/illuminators; an other one, the MSI StarCam 370i 0c45:60c0, has an infra-red light. That's why I proposed to have bit fields in the control value to switch on/off each LED.
