Cannot grab image from Xtion Pro Live with Opencv code

Question

I am using OpenCV 2.4.10 and I want to take image from my Asus Xtion Pro Live. When I'm trying to execute the code below, I get this error: "Can not open capture." I tried everything, like Sensor update, opencv with openni compiling and opencv re-installing (even the version 2.4.6).

OpenNI and Sensor are working properly since I am able to run examples such as NiViewer. But the example openni_capture.cpp (on opencv-2.4.10/samples/cpp) cannot run properly.

The code:

#include "opencv2/opencv.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include <iostream>

using namespace cv;
using namespace std;
int main(int argc, char* argv[])
{
VideoCapture capture;
    capture.open(CV_CAP_OPENNI_ASUS);
    if ( !capture.isOpened() )
    {
    cout << "Error opening capture" << endl;
    return -1;
    }
    if( !capture.grab() )
    {
    cout << "Can not grab image" << endl;
    }
    return 0;
}

The compiling is done with the following command: g++ capture.cpp -o capture pkg-config --cflags opencv --libs opencv

How can i fix this error? Is there any problem with the opencv version that i use?

I did what is being said on Can not grab image from VideoCapture OpenCV with Asus Xtion Pro Live but the problem still exists.

What serial ports are listed when you print out the list as you're doing ? Have you checked to see what serial port your camera is connected to ? On Linux you can list mounted devices with :
