来分析一个UVC的摄像头的枚举信息

使用到工具USBlyzer导出数据，但是会发现一些还有部分解析未完全。我们将借助UVCView.x86(https://files.cnblogs.com/files/libra13179/77772349UVCView.x86.rar)来进一步来分析。(懒人专用)

 补充一下关于Layout of a GUID Data Structure

 

Therefore, for a GUID defined as {32595559-0000-0010-8000-00AA00389B71}, as described
in the table above, the little-endian byte-stream representation would be:
0x59, 0x55, 0x59, 0x32, 0x00, 0x00, 0x10, 0x00, 0x80, 0x00, 0x00, 0xAA, 0x00, 0x38, 0x9B, 0x71
