So we have 2 options:

- Option A:

   1st USB + 3.0 ----> USB Host 3.0

   2nd USB ----> USB HUB -----> USB WIFI
                                        -----> USB BT
                                        -----> USB Audio
                                        -----> USB STM32F072


- Option B:

  1st USB ---> FE 1.1 --> USB Host 2.0
                                --> USB WIFI
                                --> USB BT
                                --> USB Audio

  2nd USB ---> STM32F072

-------------

What should we use?

Option A is the most complete, but if option B is the most compatible...

Thanks.
