Will STM32H743BIT6 support only OTG_HS mode?

Will it support normal USB operations by disabling OTG option? If yes which pin will control that functionality?

Hello @Meghna and welcome to the ST community,

What do you mean by normal USB operations? USB 2.0 or what?

Considering USB 2.0 HS & FS operations are different from USB 2.0 HS & FS OTG operations, Correct me if I am wrong

This this what the reference manual is telling / chapter 57 USB on-the-go high-speed (OTG_HS):
