USB接收不到数据

2019-07-20 05:43发布

请问各位,本人要用STM32F407枚举成USB HID自定义设备,用STM32_USB-Host-Device_Lib_V2.1.0中的Joystick Mouse进行修改,
现在的状况是MCU可以正确发送数据给PC,反过来,PC发送数据给MCU时,MCU却收不到,程序可以进DCD_HandleRxStatusQueueLevel_ISR(pdev)中断,
但不能进入DCD_HandleOutEP_ISR(pdev)中断
DCD_HandleRxStatusQueueLevel_ISR中断中读取FIFO的数据,发现不是PC发过来的数据。
请问MCU程序中要在哪个函数中收取PC发来的数据?是不是要进入 DCD_HandleOutEP_ISR(pdev)中断才能收到正确的数据?

没人碰到过这样的问题吗?补充一下,我的枚举配置如下
