/*
** ===================================================================
** Method : CDC1_App_Task (component FSL_USB_CDC_Device)
** Description :
** Application task to be called periodically from the main
** task.
** Parameters :
** NAME - DESCRIPTION
** * txBuf - Pointer to temporary buffer used to
** transmit data over USB. Should be equal or
** greater than the endpoint buffer size. Data
** will be sent in an asynchronous way, so
** make sure the buffer is *not* on the stack.
** This buffer must be available until the
** next transmission.
** txBufSize - Size of the buffer in bytes
** Returns :
** --- - Error code, returns ERR_OK if USB
** enumeration has been finished, error code
** otherwise.
