USB Wakeup (Light-sleep Only)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
{IDF_TARGET_NAME} can wake up from Light-sleep when activity is detected on the USB 2.0 High-Speed OTG bus. This wakeup source is intended for USB device applications that enter Light-sleep while the USB host has suspended the bus, and wake up when the host resumes the bus.
This wakeup source is available only on USB-OTG capable targets with High-Speed USB support. It is not supported by USB Serial/JTAG peripherals.
The power domain for the high-speed connectivity peripherals (``ESP_PD_DOMAIN_CNNT``) must remain powered on during sleep. Use :cpp:func:`esp_sleep_pd_config` to configure this::
esp_sleep_pd_config(ESP_PD_DOMAIN_CNNT, ESP_PD_OPTION_ON);
:cpp:func:`esp_sleep_enable_usb_wakeup` function can be used to enable this wakeup source.
