stm32f407用cubmx生成HID，改成自定义设备遇到问题

各位大神，我用的是STM32F407，先用CUBMX生成了一个HID设备，然后改成自定义的设备，现在是接收数据正常，发送数据不正常，发送用的是这个函数USBD_LL_Transmit(pdev, 0x82, txbuff2, 8);  接收用的是这个函数USBD_LL_PrepareReceive(pdev,CUSTOM_HID_EPOUT_ADDR1,rxbuff2,8);
static uint8_t  USBD_CUSTOM_HID_DataOut (USBD_HandleTypeDef *pdev,
                           uint8_t epnum)
{
   uint8_t i;
USBD_CUSTOM_HID_HandleTypeDef    *hhid = (USBD_CUSTOM_HID_HandleTypeDef*)pdev->pClassData;

if((rxbuff2[0]==0xfe)&&(rxbuff2[1]==0xa1))

}

//  USBD_CUSTOM_HID_HandleTypeDef    *hhid = (USBD_CUSTOM_HID_HandleTypeDef*)pdev->pClassData;
//
//  ((USBD_CUSTOM_HID_ItfTypeDef *)pdev->pUserData)->OutEvent(hhid->Report_buf[0],
//                                                          hhid->Report_buf[1]);
//
//  USBD_LL_PrepareReceive(pdev, CUSTOM_HID_EPOUT_ADDR , hhid->Report_buf,
//                      USBD_CUSTOMHID_OUTREPORT_BUF_SIZE);

  return USBD_OK;
}

以上是处理过程

只发出一个？

现在已经解解决了，是应为FIFO没有配置好，因为我用了两个端口HAL_PCDEx_SetRxFiFo(&hpcd_USB_OTG_FS, 0x80);
HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_FS, 0, 0x40);
HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_FS, 1, 0x40);
HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_FS, 2, 0x40);
