    How to send a code to PC Host software  in UVC firmware



        In my UVC firmware, when a GPIO key pressed, in the GPIO interruption function I want to send a code like 0xFF to PC Host software, so it can take some action like take a photo. I have tried to CyU3PUsbSendEP0Data() function to send the code, but it always returns error code 69 (CY_U3P_ERROR_TIMEOUT). So how can I realized the function.


      Thank you very much.
