 If users enter sleep manually (via :cpp:func:`esp_light_sleep_start` or :cpp:func:`esp_deep_sleep_start`), users should be cognizant of the fact that USB Serial/JTAG controller does not work during sleep. ESP-IDF **does not add any safety check to reject entry to sleep** even if the USB Serial/JTAG controller is connected. In the case where sleep is entered while the USB Serial/JTAG controller is connected, the connection can be re-established by unplugging and re-plugging the USB cable.
 
 If users enter sleep automatically (via :cpp:func:`esp_pm_configure`), enabling the :ref:`CONFIG_USJ_NO_AUTO_LS_ON_CONNECTION` option allows the {IDF_TARGET_NAME} to automatically detect whether the USB Serial/JTAG controller is currently connected to a host, and prevent automatic entry to sleep as long as the connection persists. However, note that this option increases power consumption.
