Mbed support usb for STM32H743VIT6

Hello,

usually is good to share with us some informations about Mbed OS version, about a tool what you use and share a link of the example what you tried.

Anyway, you probably mixed something. I see above you try to setup the USB OTG aka onchip USB interface. But the code more looks like old code for old library with UART.

BR, Jan
