If this is enable/disable, why "the range and step are driver-specific"? Because there is two controls grouped. That is situation of having AUTO/MANUAL. V4L2_CID_RF_TUNER_BANDWIDTH_AUTO V4L2_CID_RF_TUNER_BANDWIDTH V4L2_CID_RF_TUNER_BANDWIDTH is valid only when V4L2_CID_RF_TUNER_BANDWIDTH_AUTO == false. regards Antti > >> + >> + >> V4L2_CID_RF_TUNER_LNA_GAIN_AUTO  >> boolean >> > > -- http://palosaari.fi/
