OpenNI：オープンに失敗しました：デバイスはセーフモードで、ストリームを開始できません！

私は、奥行き画像を取得するためにプリムセンセンスセンサーでOpenNiを使用しています。 NiViwerサンプルが正常に動作しますが、センサは、Linuxのブートの前に接続されている場合、私は実行時にNiViewerまたはOpenNiを使用して、他のプログラムは、それがこのエラーで終了します。OpenNI：オープンに失敗しました：デバイスはセーフモードで、ストリームを開始できません！

オープンに失敗しました：デバイスの中にありますセーフモード。ストリームを開始できません！

これはFULログです：

を抜き、再プラグが問題を解決し、私はそれがこのトリックなしで動作する必要があります。

私はこの問題がusbモジュールに関するものと考えます。私はカーネル2.6.39と3.0.6でこれをテストしてみた

エラーがここで発生するようです：libXnDeviceSensorV2.soXnSensorFirmware.cppを

XnStatus XnSensorFirmware::Init(XnBool bReset) 
{ 
    XnStatus nRetVal = XN_STATUS_OK; 

    // check current mode 
    XnUInt16 nMode; 
    nRetVal = XnHostProtocolGetMode(m_pDevicePrivateData, nMode); 
    XN_IS_STATUS_OK(nRetVal); 

    if (bReset) 
    { 
     // check if safe mode 
     if (nMode == XN_HOST_PROTOCOL_MODE_SAFE_MODE) 
     { 
      XN_LOG_WARNING_RETURN(XN_STATUS_DEVICE_SAFE_MODE, XN_MASK_DEVICE_SENSOR, "Device is in safe mode. Cannot start any stream!"); 
     }
