uvc camera怎么修改播放器中列出的名称
上图是我的开发板接上windows之后，在使用播放器选择摄像头的时候，看到列出来的名称有UVC Camera，现在想修改这个名称，使得播放器等能够显示自己定义的名称。尝试了修改下图中的UVC Camera字段，
结果通过usbviewer扫描之后发现device information的Child Device 1并没有被修改成功，而IAD Descriptor和Interface Descriptor被修改了。
所以，我应该怎样才能将device information中的字段修改成想要的字符串呢？希望大佬们指点一下：）
ps. 好像这个UVC Camera是注册的friendly name，但是我并不知道注册friendly name使用的是哪个地方的字符串。
感谢站长的回复！我实在linux上做的开发，然后之前群友有提到修改f_uvc.c里面字符串，我修改之后，在Ubuntu里面打开能够看到相应的改动，然后在windows使用potplayer打开，还是显示UVC Camera，在Ubuntu通过guvcview打开显示lucky UVC Camera,然后我通过USBview扫了一下，下面是摘取的一段log，发现child device2里面的值还是没有改变，我觉得可能windows就是通过这个字段来注册friendly name的，但是不知道在哪可以修改呢？

其实这与Windows的机制有关系的，比如同一个PID和VID等相同的信息，你刚开始的名字叫ABCD,后面你把字符串改成DEFG了，那么重新插入电脑无论是MIC还是摄像头还是原来的那个名字的,叫做ABCD,而不是新的DEFG.
所以你需要先在设备管理器中清除原来的设备信息。然后再插入设备，这样才能用新的设备名称来显示。
具体的操作过程可以看B站的这个视频:https://www.bilibili.com/video/BV1ye4y177TS/?spm_id_from=333.999.0.0
里面当动态创建虚拟MIC和CAMERA的时候，当我们需要改变设备名称的时候，需要先删除以前的信息。
另外如果你不想那么搞的话，就把PID和VID变了，变成一个以前没见过的，这样系统就认为是一个新的设备，重新枚举的，而如果不改，就得按我上面说的那样做，因为电脑认为是同一个设备，就用了自己以前记录的名字，而不再次获取，即使你已经变了。
