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_tUSBD_CUSTOM_HID_DataOut (USBD_HandleTypeDef *pdev,
                           uint8_t epnum)

}
}

}
// USBD_LL_PrepareReceive(pdev,CUSTOM_HID_EPOUT_ADDR1,rxbuff2,8);

//USBD_CUSTOM_HID_HandleTypeDef *hhid = (USBD_CUSTOM_HID_HandleTypeDef*)pdev->pClassData;
//

//

//                      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);

自己顶一下

楼主检查一下，发送HID有没有错。

你底层的那些东西怎么改的？

没搞过，纯粹是来赚ST币的，虽然不多，日积月累嘛

首先我没有用过cubemx,但是我对你的有点疑问
先用CUBMX生成了一个HID设备，然后改成自定义的设备，
设备描述符接口描述符 HID描述符端点描述符之类都是cubemx给你生成的?

不是，自己在基础上修改的
