USB_CoreReset fails with a TIMEOUT error.

Associate II

I am trying to run a USB HS example with external PHY on NUCLEO-F756ZG. As I count find example I have gone ahead and created code from scratch. I am using USB3300 external PHY. I have made the proper connection except for RST and +5V to the module because I do not see any RST signal when I enable USB HS in STM32Cube. I am also attaching a .ico file for reference.

I think connection should not be an issue here as USB_CoreReset  might be initializing internal blocks.
