Camera not working when we install Windows embedded 7. usbvideo.sys is missing

When we are using any Windows embedded template like Application Compatibility, there is every chance that camera may not function properly after the installation is done. Reason: 1) Drivers not getting installed properly or missing drivers. 2) Check if usbvideo.sys is available in %dir%\Windows\system32\drivers . If the driver is missing then that means you may haven't connected camera while installing the OS. Even if you have this file that doesn't mean camera will work properly.

For this please follow the below blog: http://blogs.msdn.com/b/avkashchauhan/archive/2011/03/22/opening-an-internal-http-endpoint-with-wcf-servicehost-basichttpbindings-may-cause-system-net-httplistenerexception-system-servicemodel-addressaccessdeniedexception.aspx But the catch here as the blog says, it is totally internal to the machine. External WCF clients cannot communicate with this WCF service. If you are logged in as Local user in the machine. Then run the application in elevated mode to avoid this error.
