Cannot access any camera of Acer Iconia W511

Hello everyone,

I have problems developing AR software for Acer Iconia W511. The device is a windows tablet running Windows 8. I have used Metaio SDK for AR but it requires opengl which causes the tablet to crash to desktop. I have also used IN2AR SDK for AR solution as well. When using IN2AR, the program starts but is unable to start the camera of the device. Lastly, I have created my own little program that only has a main camera and a small quad with this script on it:

 void Start()
 {
  WebcamTexture w = new WebcamTexture();
  w.Play();
  renderer.material.maintexture = w;
 
 }

this however, only returns a black texture and nothing else. I have noticed that when running the camera application of windows 8, a small blue light is lit up next to the rear camera, indicating that it is running, however, when running the small program using the above script, I am unable to get the small blue indicator light.

I have tried building the above small program for both PC and Windows Store but I am unable to get any results.
