Yes, but at the time the message is printed, it is still the value that
comes from the configuration. Then comes the probe :
>From zc3xx.h, in Vimicro/ :
    PDEBUG(0, "Sensor ID:%d",spca50x->sensor);

    sensor = zcxx_probeSensor(spca50x);

and then, sensor value is -1, leading to :
    switch (sensor) {
    case -1:
         if(spca50x->sensor == SENSOR_TAS5130C_VF0250) {
            PDEBUG(0, "Find Sensor Tas5130 (VF0250)");
        } else {
            PDEBUG(0, "Find Sensor UNKNOW_0 force Tas5130");
            spca50x->sensor = SENSOR_TAS5130CXX;
and the default to SENSOR_TAS5130CXX

Directly... I've tried all the four ports of my machine (Dell Inspiron 6400),
and got the same result on all ports.

To me, it seems that the detection done in zcxx_probeSensor() is not detecting
(or not detecting correctly) the sensor in this cam.
