+also hardware interrupt 0 on many devices) and USB D- to Port D bit 4. You may
+wire the lines to any other port, as long as D+ is also wired to INT0 (or any
+other hardware interrupt, as long as it is the highest level interrupt, see
+section at the end of this file).

+/* ------------------- Fine Control over USB Descriptors ------------------- */
+/* If you don't want to use the driver's default USB descriptors, you can

+ * flash memory, (2) fixed length static data in RAM or (3) dynamically at
+ * runtime in the function usbFunctionDescriptor(). See usbdrv.h for more
+ * information about this function.
+ * 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 usbDescriptorDevice[];
+ * char usbDescriptorConfiguration[];
+ * char usbDescriptorHidReport[];
+ * char usbDescriptorString0[];
+ * 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))
+ *
+ * The following descriptors are defined:
+ * USB_CFG_DESCR_PROPS_DEVICE
+ * USB_CFG_DESCR_PROPS_CONFIGURATION
+ * USB_CFG_DESCR_PROPS_STRINGS
+ * USB_CFG_DESCR_PROPS_STRING_0
+ * USB_CFG_DESCR_PROPS_STRING_VENDOR
+ * USB_CFG_DESCR_PROPS_STRING_PRODUCT
+ * USB_CFG_DESCR_PROPS_STRING_SERIAL_NUMBER
+ * USB_CFG_DESCR_PROPS_HID
+ * USB_CFG_DESCR_PROPS_HID_REPORT
+ * USB_CFG_DESCR_PROPS_UNKNOWN (for all descriptors not handled by the driver)
+ *
+ * Note about string descriptors: String descriptors are not just strings, they
+ * are Unicode strings prefixed with a 2 byte header. Example:
+ * int serialNumberDescriptor[] = {
+ * USB_STRING_DESCRIPTOR_HEADER(6),
+ * 'S', 'e', 'r', 'i', 'a', 'l'
