STM32H743VIT6 USB not working

[BrunoS]

Hello there! Esteemed ST team member,

I hope this message finds you well. I'm reaching out to address an issue I've encountered.

I've designed a board based on the STM32H743 Nucleo board, but unfortunately, I'm facing difficulties with the USB functionality. I'm unsure if it's a matter of configuration or firmware. When I tested USB settings and functionality using the Nucleo board, everything worked seamlessly. Therefore, I'm inclined to think that the issue might lie with my board's circuit design.

I would greatly appreciate any insights or assistance you could provide regarding this matter. Looking forward to your response.

I've confirmed that the issue was caused by not changing the setting from 144 pins to 100 pins. It's working fine now. Thank you.
