---+ USB Composite Device with MSC and CDC

STM32WB55: 16 Endpoints, Full Speed 12 Mbits/s, 8 bi-directional endpoints

Enumerate braucht Heap!

It is easy to build a stand alone USB device with !CubeMX. But if you want go a bit further and try to build a composite device, the struggle begins.

I gave up to use the STM USB middleware. It is interrupt driven, but not easy to integrate into an RTOS.
I took TinyUSB and I am very happy with it. Everything straight forward an clear.
