STM32Cube USB MW Device Library V2.11.1 and USB composite builder documentation

Dear ST,

I was not able to find any documentation for composite builder feature of your USB MW library. Is it documented somewhere?

I was able to get USB composite device running after enabling USE_USBD_COMPOSITE define. But I had to fix some bugs, that possibly exist in the library and there are still more issues to solve.

When will STM32CubeMX tool support USB composite devices?

kind regards,

Tomasz
