* capabilities. These macros may then be referenced in the user application to selectively enable or disable
* code sections depending on if they are defined or not.
*
* \note This file should not be included directly. It is automatically included as needed by the USB driver

*
* After the inclusion of the master USB driver header, one or more of the following
* tokens may be defined, to allow the user code to conditionally enable or disable
* code based on the USB controller family and allowable USB modes. These tokens may
* be tested against to eliminate code relating to a USB mode which is not enabled for
* the given compilation.
