+ *  Class drivers give a framework which sits on top of the low level library API, allowing for standard\r
+ *  USB classes to be implemented in a project with minimal user code. These drivers can be used in\r
+ *  conjunction with the library low level APIs to implement interfaces both via the class drivers and via\r
+ *  the standard library APIs.\r
+ *\r
+ *  Multiple device mode class drivers can be used within a project, including multiple instances of the\r
