The USB device stack files are available as part of ASF in Atmel® Studio.
To list relevant USB examples in Atmel Studio 7, select "New Example
Project..." from the start screen or the File menu (File → New → Example Project...). The
list of examples can be reduced to list only USB by either searching for USB in the search
field or select USB from the Technology tab.
Note: This USB device stack does not apply
to ASF examples with names containing "from ASF V1".
