This is because each interface will be loaded into a separate driver - * instance, causing the two interfaces be become unlinked. To prevent this, you - * should use the "Interface Association Descriptor" addendum to the USB 2.0 standard - * which is available on most OSes when creating Composite devices. - * - * Another major oversight is that there is no mechanism for the host to notify the - * device that there is a data sink on the host side ready to accept data. This - * means that the device may try to send data while the host isn't listening, causing - * lengthy blocking timeouts in the transmission routines. It is thus highly recommended - * that the virtual serial line DTR (Data Terminal Ready) signal be used where possible - * to determine if a host application is ready for data. - * - * @{ - */ - -#ifndef _CDC_CLASS_DEVICE_H_ -#define _CDC_CLASS_DEVICE_H_ - - /* Includes: */ - #include "../../USB.h" - #include "../Common/CDCClassCommon.h" - - #include <stdio.h> - - /* Enable C linkage for C++ Compilers: */ - #if defined(__cplusplus) - extern "C" { - #endif - - /* Preprocessor Checks: */ - #if !defined(__INCLUDE_FROM_CDC_DRIVER) - #error Do not include this file directly.
