OpenNI：「打開失敗：設備處於安全模式，無法啓動任何流！」

我使用OpenNI傳感器來獲取深度圖像。 NiViwer採樣工作正常，但如果傳感器之前的Linux啓動連接，當我運行NiViewer或使用OpenNi任何其他程序，它與此錯誤退出：OpenNI：「打開失敗：設備處於安全模式，無法啓動任何流！」

打開失敗：設備是安全模式。無法啓動任何流！

這是FUL日誌：

拔出並重新插入解決問題，但我需要它沒有這一招工作。

我想這個問題是關於USB模塊。我曾與內核2.6.39和3.0.6測試這

的錯誤似乎發生在這裏：libXnDeviceSensorV2.soXnSensorFirmware.cpp

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!"); 
     }
