+ * Descriptor handling is configured through the descriptor's properties. If
+ * no properties are defined or if they are 0, the default descriptor is used.
+ * Possible properties are:
+ * + USB_PROP_IS_DYNAMIC: The data for the descriptor should be fetched
+ * at runtime via usbFunctionDescriptor(). If the usbMsgPtr mechanism is
+ * used, the data is in FLASH by default. Add property USB_PROP_IS_RAM if
+ * you want RAM pointers.
+ * + USB_PROP_IS_RAM: The data returned by usbFunctionDescriptor() or found
+ * in static memory is in RAM, not in flash memory.
+ * + USB_PROP_LENGTH(len): If the data is in static memory (RAM or flash),
+ * the driver must know the descriptor's length. The descriptor itself is
+ * found at the address of a well known identifier (see below).
+ * List of static descriptor names (must be declared PROGMEM if in flash):

+ * char usbDescriptorHidReport[];

+ * int usbDescriptorStringVendor[];
+ * int usbDescriptorStringDevice[];
+ * int usbDescriptorStringSerialNumber[];
+ * Other descriptors can't be provided statically, they must be provided
+ * dynamically at runtime.
+ *
+ * Descriptor properties are or-ed or added together, e.g.:
+ * #define USB_CFG_DESCR_PROPS_DEVICE (USB_PROP_IS_RAM | USB_PROP_LENGTH(18))
