    CX3 high speed YUV upstream is temporarily blocked with UVC GET request.

      Hi,

       

      I have some problem about YUV upstream and UVC GET request.

       

      The YUV 640x480@30 preview is ok when there is no UVC CONTROL request.

      But if there is a UVC GET request on the USB HIGH SPEED connection,

      YUV upstream is blocked and 'CyU3PDmaChannelCommitBuffer' throws error.

       

      Is this some kind of bandwidth limitation? or bandwidth reservation for USB CONTROL endpoint?

       

      Any advice and suggestions will be greatly appreciated.

       

      Environment:

        Sensor: Samsung M3085

        Device : CX3 (512KB), SDK: 1.3.3 or 1.3.4

        Preview : AmCap

       

      Thanks in advance.
