The device supprt brings support for multiple stack instances, multiple configuration, asynchronous transfer model, ability to change most of the properties of a device at runtime and the composition of configuration and classes at runtime. The stack requires new UDC driver API and is not compatible with old driver API (usb_dc_). The classes (functions) of old (current) USB device stack cannot be used with new ones and must be ported.
