STM32F429 USB CustomHID 0x82端点发送不出数据

CharlesP · 发表于 2020-5-7 23:41:29

使用原子哥的MSC工程里USB驱动文件，修改usbd_customhid_core.c中的配置描述符，枚举成custom HID设备，用#define HID_IN_EP                   0x82#define HID_OUT_EP                0x02
枚举成功，可以正常接收PC发送的数据，但是调用函数
USBD_CUSTOM_HID_SendReport()
发送数据到PC使用BUS BOUND监听确接收不到STM32发送的数据。
改成
#define HID_IN_EP                   0x81#define HID_OUT_EP                0x01

就能正常收发了
是哪个描述符没有配置对，还是别的什么原因呢？请大家指教

下面是我的配置描述符和报告描述符
