Example description
The example shows how to us USBD LIB stack to creates a USB to UART converter port.

Special connection requirements
Connect the USB cable between micro connector on board and to a host.
When connected to Windows host use the .inf included in the project
directory to install the driver. For OSx (Mac) host, no drivers are needed.

Base Board J14 needs to be moved to short pins 2 and 3.

On EA Devkit 1788/4088 board jumper J15 must be closed, for the device
to be detected.
