阿莫电子网找了一个STM32F4单片机实现USB-Hid设备的程序，编译及烧录都正常，设备也能够被正确枚举及打开，但是USB调试助手始终无法收到数据。用"Bus Hound"工具看数据包，可见如下错误信息（红 {MOD}字体）：

不知是否有人遇到类似错误？请问是如何解决的？

//USB Device 配置成功
void USBD_USR_DeviceConfigured (void)
{
//bDeviceState=1; <-----------
printf("MSC Interface started. ");
}
//USB Device挂起
void USBD_USR_DeviceSuspended(void)
{
//bDeviceState=0; <-------------
printf("Device In suspend mode. ");
}
//USB Device连接成功
void USBD_USR_DeviceConnected (void)

printf("USB Device Connected. ");
}
//USB Device未连接
void USBD_USR_DeviceDisconnected (void)
{

printf("USB Device Disconnected. ");
}
则不会出现"babble detected"以及后边的错误了，但是数据还是接收不到。
---------------------------------
你好，后续是否能开发USB-hid设备作为device的例程及视频。目前比host的需求多。
