.. option:: CONFIG_CDC_ACM_DTE_RATE_CALLBACK_SUPPORT

*Support callbacks when the USB host changes the virtual baud rate*

Type: ``bool``

Help
====

.. code-block:: none

    If set, enables support for a callback that is invoked when the
    remote host changes the virtual baud rate. This is used
    by Arduino style programmers to reset the device into the
    bootloader.
