USB web cam does not get detected.

Hello,

I am trying to interface a USB web cam on beaglebone black android. I can see the device is created as /dev/video0 but when I call getNumberOfCameras() from my application code it always return 0. Is there a limitation in Android on connecting USB camera?

Any Idea how to fix it and how get handle of camera in app?

Thanks,
Gaurav
