stm32F446 USB复合CDC及MSC
大家好！我现在做USB复合设备，参照网上了代码完成了复合设备代码的修改。但是现在遇到一个问题，就是CDC和MSC设备同时只能识别出一个来。我在其它部分代码不变动的情况下如果将PID设置为：
#define USBD_PID_FS 22336
就可以识别出CDC设备；
设置为：
#define USBD_PID_FS 22314
就可以识别出MSC设备；
但是就是不能同时识别出CDC和MSC，麻烦各位指导一下；
下面是参考网上复合设备的描述

修改PID会导致驱动安装错误吧，需要写个inf文件 斜阳__ 发表于 2018-11-28 09:50
修改PID会导致驱动安装错误吧，需要写个inf文件
谢谢你的解答！但是我遇到的问题还不是安装不了驱动，而是连设备也没识别到。如果是识别到了两个设备打个感叹号估计都好处理一点。 您的后来搞定了吗？我用F7 也没有找到办法
