STM32F407ZG单片机USB-Hid通讯PC无法收到数据问题

phmatthaus · 发表于 2015-12-22 14:41:07

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（红色字体）：

不知是否有人遇到类似错误？请问是如何解决的？

在实验中发现，将USB\USB_APP\usbd_usr.c中的带箭头内容的代码注释掉，换到下面的函数中
//USB Device 配置成功
void USBD_USR_DeviceConfigured (void)
{
//bDeviceState=1;    <-----------
printf("MSC Interface started.\r\n");
}
//USB Device挂起
void USBD_USR_DeviceSuspended(void)
{
//bDeviceState=0;  <-------------
printf("Device In suspend mode.\r\n");
}

//USB Device连接成功
void USBD_USR_DeviceConnected (void)
{
bDeviceState=1;  ++---------------------
printf("USB Device Connected.\r\n");
}
//USB Device未连接
void USBD_USR_DeviceDisconnected (void)
{
bDeviceState=0;    ++-------------------
printf("USB Device Disconnected.\r\n");
}

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。
