请教各位大佬，我最近使用F405芯片，用stm32CubeMX默认创建了一个USBHID的例程，这个例程默认就是一个HID模拟鼠标移动的程序，我创建之后也是可以正常枚举并且鼠标正常移动的，说明生成的工程是没有问题的，然后我把报告描述符修改成了一个多点触摸的描述符，这个描述符是以前项目使用的，是没有问题的。变量也没有改变，只是把报告描述符的内容替换了，如下图：4 G$ D1 O9 }0 ]
这个报告描述符字节比较大，又474个字节，然后我又把相应的配置描述符修改了，如下图所示：) I& i1 Z- |3 b, V5 J3 X 把配置描述符集合里HID描述符中描述报告描述符大小的字节改成我们修改后的大小，如下图 
按道理，将这些修改之后，就相当于重新约定了HID上报数据的协议，随后，我又按照新规定的报告描述符的协议模拟上报触控点的数据。 通过Bus hound显示枚举是成功的，也一直在按照报告描述符规定的协议向主机发送数据，但是没有模拟触控的现象，我使用以前的工程是有明显 的触控屏幕的现象的。通过设备管理器查看设备是正常运行的，然后用Bus hound观察枚举过程，发现一直在上报数据，但是在枚举过程中在主机! M* Z. g& F6 a6 [, a 发送GET_REPORT之后出现了USTS c0000004 stall pid 错误，出现之后枚举也没有停止，而是正常运行的，数据也是正常上报的， 但就是没有现象，我感觉是主机没有接收到报告描述符，或者接收错误了，导致虽然数据是正常上报的，但是系统不知道上报的数据的含义，: [" Q( j( F6 ^ C( N8 e 有没有大佬懂得这方面的错误，还请指导一下，工程其他地方都没有动，就是修改了配置、报告描述符等信息。& X5 q4 f- ^6 y/ G
