4.2. LUFA USB Stack

The USB CDC firmware example is based on the LUFA open-source project. LUFA is an open-source complete

USB stack released under the permissive MIT License. It includes support for many USB classes, both for USB

Hosts and USB Devices. For USB Devices, the LUFA stack includes support for Audio Class, CDC Class, HID

Class, Mass Storage Class, MIDI Class, and RNDIS Class.
