STM32F7 USB host CubeMX does not detect USB pendrive if it is inserted before reset

STM32F7 USB HS host, in FS speed, with external PHY, no VBUS control (always on). The stack fails to detect USB pendrive if it is inserted before reset. I found there is interrupt but seem like the driver does not in correct state so it does not get processed correctly. Anyone has any idea?
