Why BeagleBone Is not able to take camera Input using Open CV for python ?

Enter code here...

I am doing Live Video streaming using the camera Logitech C310 on BeaglBone Black. For checking whether it is working, I wrote a basic code for getting the frame and printing the frame in its array form but I always get an empty array. I tried the same code on my laptop with the same camera, In which I get some value. I don't why I am getting like this in Beaglebone black, Here is the code as well as the sample output. I have installed opencv 2.4.9.1 in beaglebone but opencv 3.0.0 in my laptop.

Code

import numpy as np
import cv2

cap = cv2.VideoCapture(0)

while True:
  ret, frame = cap.read()
  print ret
  print frame

cap.release()

Output from BeagleBone Black
