Hello Mayur, I am afraid I cannot help you. I didn't manage to get rid of this problem, my only "solution" was to restart the mote, which seems to confirm that the problem is from the mote, but it can also be the USB driver. Right now I don't work with motes anymore, so I cannot try anything. I hope you'll find something out, I remember that it was a rather frustrating problem.
