Previously, reset over USB CDC was done by calling esp_restart from an interrupt handler. This works only until some restart hook function is registered using esp_register_shutdown_handler, and the hook function tries to do something that isn’t allowed in an interrupt handler. One such case is with Wi-Fi. When Wi-Fi driver is installed, it registers esp_wifi_stop as a shutdown handler function. However esp_wifi_stop cannot be called from an ISR, and hence we shouldn’t call esp_restart from an ISR either. This commit modifies USB CDC driver to call esp_restart by posting it to esp_timer task. Closes https://github.com/espressif/esp-idf/issues/7404
