Kinect with libfreenect through ros with python script

edit

I am using my Kinect with libfreenect driver. My python script works fine when I use it on my desktop with Kinect connected. Glview works fine too. With my Kinect connected to my robot laptop,I ran to roscore on it and rosrun my python script on desktop. it is unable to identify freenect.sync_get_video, asking if my device is connected. Does libfreenect works through ros? By the way roslaunch freenect_launch freenect.launch works just fine. The website I am referring to is https://naman5.wordpress.com/2014/06/...
