Regarding STM32Cube USB device library .
I am using the stm32f411ce micro with the PT1 device.
I have noticed that after downloading the elf file via stlink the to the PT1 device the USB host stopped to detect him over the the USB bus.
After some debugging I am getting at the HAL_PCD_IRQHandler() function at the stm32f4xx_hal_pcd.c file .
first I entered to __HAL_PCD_CLEAR_FLAG(hpcd, USB_OTG_GINTSTS_MMIS);
meaning incorrect mode , what's that means , what is wrong here.
second the USB HOST trying to do
MEANING the PT1 is in SUSPEND MODE.
and than __HAL_PCD_GET_FLAG(hpcd, USB_OTG_GINTSTS_ENUMDNE)
meaning Handle Enumeration done Interrupt.
How could I debug it.
