This board connects the USB HS interface to the micro usb connector as opposed to the USB FS interface on the stm32f4-discovery board. This is why we are using different pins, different periph and different driver. At the end it should(TM) behave the same as the HS interface implements FS too.

This example implements a USB MIDI device to demonstrate the use of the
|
|
USB device stack. It implements the device configuration found in Appendix
|
|
B of the Universal Serial Bus Device Class Definition for MIDI Devices.
|
|
|
|
The 'USER' button sends note on/note off messages.
|
|
|
|
The board will also react to identity request (or any other data sent to
|
|
the board) by transmitting an identity message in reply.
