STM32L475 USB OTG Host GPIO Interrupt Failed

i have a STM32L475 with USB OTG as Host with USB Disk attached and an GPIOInt with callback void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin).


If i build my HAL without USB all is ok, but when i build it with USB Support, the callback is never called anymore.


Can anybody help me (I have tested to set the usb Priority to 1 and the GPIOInt to 0 but it had failed).


Best Regards
