    USBVideoClass firmware : Device not steaming when trying to configure UVC descriptors to send YUY2 images

    sad.ferradji

      Hello,

         

      I tried to modify the descriptors in the firmware project "USB Video Class Bulk" provided with the SDK. The descriptors are originally configured to stream MJPEG images stored in "vidframes" structure. When "Class specific VS format" and "Class specific VS frame" descriptors are modified to stream YUY2 images, the device is successfully recognized by host but cannot begin streaming any data. In "MJPEG mode" it works correctly.

         

      The attached text file contains the descriptors and other structures I've modified.

         

      Did anyone get the same problem and solved it ?

         

       

         

      Regards.
