How to receive USB resume signal from host when STM32F407 send remote wakeup signal

[Harry0709]

Environment:

STM32F407VGTX 

USB HID mouse, Full Speed

Problem:

Hi, I’m using a STM32F407VGTX board. I send a USB remote wakeup signal to the host and then try to receive a resume signal from the host. The STM32 board can wake up the host (bringing it to the login screen), but it cannot trigger the USB_OTG_GINTSTS_WKUINT interrupt. I have already configured my STM32 board as a HID mouse. However, if I use a real mouse instead, it can wake up the host and successfully trigger the USB_OTG_GINTSTS_WKUINT interrupt. Is there any suggestion or workaround for this problem?

void usb_remote_wakeup()
{
    if (hUsbDeviceFS.dev_remote_wakeup == 1)
    {
        __HAL_PCD_UNGATE_PHYCLOCK(&hpcd_USB_OTG_FS);
        HAL_PCD_ActivateRemoteWakeup(&hpcd_USB_OTG_FS);
        HAL_Delay(5);
        HAL_PCD_DeActivateRemoteWakeup(&hpcd_USB_OTG_FS);
    }
}

Hello @Harry0709 

You can refer to the USB HID application available in the STM32CubeF4 firmware:

HID application support remote wakeup 

If you are not able to trigger the USB_OTG_GINTSTS_WKUINT interrupt, you can share with me how you are trying to trigger it, and I will help you
