* 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.
