+ *  The following files must be built with any user project that uses this module:
+ *    - LUFA/Drivers/USB/Class/Device/CDCClassDevice.c <i>(Makefile source module name: LUFA_SRC_USBCLASS)</i>
+ *
+ *  \section Sec_USBClassCDCDevice_ModDescription Module Description
+ *  Device Mode USB Class driver framework interface, for the CDC USB Class driver.
+ *
+ *  \note There are several major drawbacks to the CDC-ACM standard USB class, however
+ *        it is very standardized and thus usually available as a built-in driver on
+ *        most platforms, and so is a better choice than a proprietary serial class.
+ *
+ *        One major issue with CDC-ACM is that it requires two Interface descriptors,
+ *        which will upset most hosts when part of a multi-function "Composite" USB
+ *        device. 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
