* - The USBtoSerial demo now discards all data when not connected to a host, rather than buffering it for later transmission.
* - Most demos, bootloaders and applications have had their control request handling code corrected, to properly send the status
* stage in all handled requests. If you are using code based off one of the library demos, bootloaders or applications, you should
* update to the latest revisions.

* <b>Non-USB Library Components</b>
