*
* \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
* to determine if a host application is ready for data.
