Hi guys, having an issue getting the DFU mode working again.

Learning from my last mistake where I didnt connect the USBV33V last time, however this time I did.

The computer is detecting the MCU, but I guess the MCU for whatever reason does not want to say its descriptor, any reason why?

MCU: stm32h753zit6

    Issues was hardware. The physical USB 2.0 Micro was not seated properly even after doing it 5 times.
