* at runtime via usbFunctionDescriptor().
* + 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:
