* App_USBD_CDC_EEM_Init()
*
* Description : Initialize USB device CDC EEM subclass.
*
* Argument(s) : dev_nbr Device number.
*
* cfg_hs Index of high-speed configuration to which this interface will be added to.
*
* cfg_fs Index of high-speed configuration to which this interface will be added to.
*
* Return(s) : DEF_OK, if successful.
* DEF_FAIL, otherwise.
*
* Note(s) : (1) This function assumes that uC/TCP-IP with USBD_CDCEEM driver is part of the project
* and that it has been initialized.
*
* (2) This example will set a static IPv4 address to the interface. For more examples that
* uses IPv6 and/or assignation of address via DHCP, see uC/TCP-IPs application
* examples.
