STM32F207的HOST usb 非常有用，可以接U盘,也可以接USB接口的键盘。非常方便，但ST的U库V2.0,V2.1实际使用都有问题。
经过修改，现在可以很好第读写U盘和连接HID键盘。
程序代码的核心是V2.1的库。
通过U盘D读写，可以方便地进行IAP-BOOT操作。以及用户键盘操作！

初始化端口程序：
void USB_OTG_BSP_Init(USB_OTG_CORE_HANDLE *pdev){
  GPIO_InitTypeDef GPIO_InitStructure;
  RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOB , ENABLE);

  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_12  |
GPIO_Pin_13 |
   GPIO_Pin_14 |
      GPIO_Pin_15;

  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF;
  GPIO_Init(GPIOB, &GPIO_InitStructure);

  GPIO_PinAFConfig(GPIOB,GPIO_PinSource12, GPIO_AF_OTG2_FS) ;
  GPIO_PinAFConfig(GPIOB,GPIO_PinSource13,GPIO_AF_OTG2_FS) ;
  GPIO_PinAFConfig(GPIOB,GPIO_PinSource14,GPIO_AF_OTG2_FS) ;
  GPIO_PinAFConfig(GPIOB,GPIO_PinSource15,GPIO_AF_OTG2_FS) ;
//---------------------------------------------------------------
  RCC_AHB1PeriphClockCmd( RCC_AHB1Periph_OTG_HS, ENABLE) ;
//-----------------------------------------------------------------
//Vbus_EN 根据实际电路修改！
  RCC_AHB1PeriphClockCmd( RCC_AHB1Periph_GPIOE , ENABLE) ;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_OUT;
GPIO_InitStructure.GPIO_Pin =  GPIO_Pin_0;
  GPIO_InitStructure.GPIO_OType = GPIO_OType_PP;
  GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP ;
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz;
  GPIO_Init(GPIOE, &GPIO_InitStructure);

GPIO_ResetBits(GPIOE, GPIO_Pin_0);
//-------------------------------------------------------------------
  USB_OTG_BSP_TimeInit();
USB_OTG_BSP_mDelay(500); //Delay is need for stabilising the Vbus Low

RE:【MCU实战经验】STM32F207的host USB的MSC和HID的合并开发

采用内部的：USE_EMBEDDED_PHY ，所以直接用IO连接U端口。

RE:【MCU实战经验】STM32F207的host USB的MSC和HID的合并开发

主程序非常简单：（这里是用U盘iap—BOOT为例）：
int main(void){

  /*!< At this stage the microcontroller clock setting is already configured,
  this is done through SystemInit() function which is called from startup
  file (startup_stm32fxxx_xx.s) before to branch to application main.
  To reconfigure the default setting of SystemInit() function, refer to
  system_stm32fxxx.c file
  */

  /* Init Host Library */
  USBH_Init(&USB_OTG_Core,
         USB_OTG_HS_CORE_ID,
         &USB_Host,
         &USBH_MSC_cb,
         &USR_cb);

  while (1){
/* Host Task handler */
USBH_Process(&USB_OTG_Core, &USB_Host);
if(iapRun==0){
IAP_URN_UserProgrammer();
}
  }
}

RE:【MCU实战经验】STM32F207的host USB的MSC和HID的合并开发

由于HOST-MSC和HID的初始化全部相同，这里先不介绍，不同点是从枚举后分析数据协议开始，所以我们在这里添加设备识别代码，然后再根据不同的设备，做相应的事情，这里主要是MSC的处理和HID设备的处理，同样也可以添加其他的设备.
  case HOST_USR_INPUT:
/*The function should return user response true to move to class state */
   //修改：添加MSC-HID自动判别，然后再初始化CALSS-CB
if(JB_MSC_HID(phost,0)){ //0:判别MSC，1：判别HID
SetHOST_USB_MODE(0);
phost->class_cb=&USBH_MSC_cb;
if((phost->class_cb->Init(pdev, phost)) == USBH_OK){
phost->gState  = HOST_CLASS_REQUEST;
}
}else{
if(JB_MSC_HID(phost,1)){ //0:判别MSC，1：判别HID
SetHOST_USB_MODE(1);
phost->class_cb=&HID_cb;
//phost->usr_cb=&USR_Callbacks;//???????
if((phost->class_cb->Init(pdev, phost)) == USBH_OK){
phost->gState  = HOST_CLASS_REQUEST;
}
}
}
break;

case HOST_ENUMERATION:
/* Check for enumeration status */
if ( USBH_HandleEnum(pdev , phost) == USBH_OK){
   /* The function shall return USBH_OK when full enumeration is complete */

   /* user callback for end of device basic enumeration */
   phost->usr_cb->EnumerationDone();

   phost->gState  = HOST_USR_INPUT;

RE:【MCU实战经验】STM32F207的host USB的MSC和HID的合并开发

这是判别代码：
//修改：添加MSC-HID自动判别，然后再初始化CALSS-CB
unsigned char JB_MSC_HID(USBH_HOST *phost,unsigned char flag){//0:判别MSC，1：判别HID

if(flag==0){
if(phost->device_prop.Itf_Desc[0].bInterfaceClass == MSC_CLASS){
if(phost->device_prop.Itf_Desc[0].bInterfaceProtocol == MSC_PROTOCOL) return 1;
}
}else{
if(phost->device_prop.Itf_Desc[0].bInterfaceSubClass == HID_BOOT_CODE) return 1;
}
return 0;
}
