+   image sensors connected to the SN9C1XX bridges. The entire API is documented
    below. In the most general case, to support a sensor there are three steps
    you have to follow:
    1) define the main "sn9c102_sensor" structure by setting the basic fields;
    2) write a probing function to be called by the core module when the USB
       camera is recognized, then add both the USB ids and the name of that
-      function to the two corresponding tables SENSOR_TABLE and ID_TABLE (see
-      below);
+      function to the two corresponding tables in sn9c102_devtable.h;
    3) implement the methods that you want/need (and fill the rest of the main
       structure accordingly).
