This example application demonstrates using a USB
Communications Device Class for hosting a FTDI FT232R device.
I m using FTDIs UB232R development module:

Which has this FTDI chip:

It has USB_CLASS_VEND_SPECIFIC (0xff) Interface Class.
Other CDC drivers could also be added to this example in the future (ACM, Prolific,...).
