I'm use USB3320 with STM32H753.
And I want to control USB3320 with ULPI operation to boost drive strength.
Is there any method? I can't found solution both in HAL API and register.
Thanks.

I know that there is a STM32F769I-DISCO example code that controls hidden secret register to access USB PHY through ULPI.
I can't find similar example for H7, but it would worth to try.
Good luck.
