最近在学习libusb-win32，因此拿STM32F4写了个下位机，然后和上位机一起进行测试
这个是HID的测试程序，上位机和下位机都测试通过

//STM32主程序，非常的简答

int main(void)
{
uint8_t buf[16] = {0,1,2,3};
RCC_ClocksTypeDef RCC_Clocks;
/* SysTick end of count event each 10ms */
RCC_GetClocksFreq(&RCC_Clocks);
SysTick_Config(RCC_Clocks.HCLK_Frequency / 100);
//ÅäÖÃUSB HID
USBD_Init(&USB_OTG_dev,
USB_OTG_FS_CORE_ID,
&USR_desc,
&USBD_HID_cb,
&USR_cb);
while(1)
{
Delay(1);
buf[0]++;
USBD_HID_SendReport (&USB_OTG_dev, buf, 4);
}
}
