Wire-shark capture , seems in STM32F446 , enumeration process fails from SET ADDRESS REQUEST. Same code works fine on stm32F407 and 429

incorrect work on f412:
Numbers are milliseconds.
Here it could be seen, that after first USBRESET MCU receives GET DEV DESCR request, host receives reply then it issues a second USBRESET and nothing happens. After about a second I perform MCU reset and host issues USBRESET and once again USBRESET and send SETUP ADDRESS.
It is very strange. Seems like host waits for some line state. Or maybe MCU does not see SETUP ADDRESS from first attempt.
