I like my new HXSD, but I really need a camera. I have tried several UVC-compliant USB cameras
with external-USB-cam apps from the Google Play Store (like Webeecam). These programs ask me to
plug in my camera, and seems to notice when I do that. But they display any video. These cameras
only require 200mA of current, which is will within the 500mA limit for a standard USB2 output.
It there some reason this will not work? Is there something else I should do?
Thanks!

Using an app called CameraFi I can confirm that the camera is connected. I can see the camera name, and I can choose the resolution, compression, and frame rate. But I cannot see any video.
