STM32 + EXPHY USB3300 + VBUS Sensing

Dear All.

Based on HAL library, I make small project where I have USB HS with external PHY (USB3300) and CDC class. Works well. What I need is to implement Vbus sensing. This can be done only via external phy, there are some flags in registers to enable it, but I don’t know how make it working. I got a few question:

1.      Can current HAL library enable vbus sensing in the USB3300 chip?

2.      Is it possible to have access to the ULPI communication to setup those registers and bit manually?
