Thanks for the answers. Did you refer to the following?

How could I implement a flash device? Do you mean I need to take some 
existing USB device created by AVR and replace its firmware by LUFA or 
something like that? Could I use that modified USB device on every PC or 
operation system?

Kind regards,
