A number of the STM32F4xx devices are equipped with two USB ports, one FS (Full Speed) and one HS (High Speed). The HS port has a built-in FS PHY, but to achieve HS, an external PHY is necessary.
Enabling USB HS port in Stm32CubeMX reveals the pinpout:
Clock
To save a crystal, the STM32F4xx can be driven by a 24 MHz crystal, which is then outputted on MCO1:
