Class Drivers
*************

Class drivers implement USB protocols such as CDC serial, HID, mass storage,
and MIDI.  Enable only the classes your product uses: device APIs start with
``tud_`` and host APIs start with ``tuh_``.

Start with :doc:`device` or :doc:`host`, then use the class page for its
configuration, data flow, callbacks, and examples.  The API lists below focus
on the calls normally needed by an application; the public headers remain the
complete API reference.
