uvcvideo：终端4没有找到流媒体接口

我正在尝试将UVC应用程序与另一个应用程序集成。它造成以下错误。没有为终端4找到流媒体接口
但是Linux系统识别UVC相机并枚举它。附加了屏幕截图和描述符文件。这可能是什么原因呢？
我还附加了我的USB描述符文件。我已经注释了USB2，USB1描述符，使事情更简单。我用的是USP3的电脑，所以这不是问题。

  I am trying to integrate UVC application with another application.
It is throwing the following error. "No streaming interface found for terminal 4"

But the linux system recognises the uvc camera and enumerates it. Have attached screenshot and descriptor file.
What might  be the reason for this?





I have also attached my USB descriptor file.
P.S I have commented out u***2,u***1 descriptor to make things simpler. I am using a computer with USB3 so it is not a problem.
