ardrone driver system hang

Can you please help me here?

Recently, I got a new HP - Pavilion g6-2313AX 64 bit laptop, installed windows 8 and ubuntu 12.04 in it. I wanted to control drone from this laptop and installed necessary software in ubuntu. The package ardrone_autonomy was successful without errors.

This Ardrone 2.0 am trying to control is also a brand new one, I got just yesterday from amazon.com. I do the following to control it using ardrone_driver

roscore

(new terminal)

roscd ardrone_autonomy

rosrun ardrone_autonomy ardrone_driver

This is where am facing the problem. Either of the following 4 occurs, but system hang is occuring in all cases
