STM32H743 USB ports are not recognized by windows

[T J]

both ports set to CDC using internal PHY

Heap set to 0x2000

VBus sensing not utilized, but that should only affect 1 port, not both.

using Cube_MX on this new project.

Is there example code for H7 using USB ?

Fixed it, the Crystal wasn't running, re-flowed and fixed.

Now Windows recognizes both ports without the use of VBus sensing.

Interesting how without a crystal, it doesn't work with the internal RC48 oscillator
