+			 *                      mode speed.
+			 *
+			 *  \note To reduce the FLASH requirements of the library if only device or host mode is required,
+			 *        the mode can be statically set in the project makefile by defining the token \c USB_DEVICE_ONLY
+			 *        (for device mode) or \c USB_HOST_ONLY (for host mode), passing the token to the compiler

+			 *        this function). To statically set the USB options, pass in the \c USE_STATIC_OPTIONS token,
