Example: Sensor configuration file for USB camera

When there's only one USB camera connected to the board, you can use wildcards in the address parameter, which are denoted by four -1 values. Here's what the configuration file looks like:

begin SENSOR_UNIT_1
    type = usb_camera
    name = front
    position = 0, 0, 0
    direction = 0, 0, 1
    address = /dev/usb/io-usb-otg, -1, -1, -1, -1
end SENSOR_UNIT_1
