What is the expected behavior?

The code below is from an example, but it lacks the deinit (cleanup) part. I've tried implementing deinit myself, but the system always crashes. Please provide code that safely deinitializes the USB functionality.

/* Initialize default TCP/IP stack */
ESP_ERROR_CHECK(esp_netif_init());
ESP_ERROR_CHECK(esp_event_loop_create_default());

esp_event_handler_register(IOT_ETH_EVENT, ESP_EVENT_ANY_ID, iot_event_handle, NULL);

// install usbh cdc driver
usbh_cdc_driver_config_t config = {
    .task_stack_size = 1024 * 4,
    .task_priority = 5,
    .task_coreid = 0,
    .skip_init_usb_host_driver = false,
};
ESP_ERROR_CHECK(usbh_cdc_driver_install(&config));

iot_usbh_rndis_config_t rndis_cfg = {
    .auto_detect = true,
    .auto_detect_timeout = pdMS_TO_TICKS(1000),
};

iot_eth_driver_t *rndis_handle = NULL;
esp_err_t ret = iot_eth_new_usb_rndis(&rndis_cfg, &rndis_handle);
if (ret != ESP_OK || rndis_handle == NULL) {
    ESP_LOGE(TAG, "Failed to create USB RNDIS driver");
    return;
}

iot_eth_config_t eth_cfg = {
    .driver = rndis_handle,
    .stack_input = NULL,
    .user_data = NULL,
};

iot_eth_handle_t eth_handle = NULL;
ret = iot_eth_install(&eth_cfg, &eth_handle);
if (ret != ESP_OK) {
    ESP_LOGE(TAG, "Failed to install USB RNDIS driver");
    return;
}

esp_netif_config_t netif_cfg = ESP_NETIF_DEFAULT_ETH();
esp_netif_t *eth_netif = esp_netif_new(&netif_cfg);

iot_eth_netif_glue_handle_t glue = iot_eth_new_netif_glue(eth_handle);
if (glue == NULL) {
    ESP_LOGE(TAG, "Failed to create netif glue");
    return;
}
esp_netif_attach(eth_netif, glue);

while (1) {
    ret = iot_eth_start(eth_handle);
    if (ret != ESP_OK) {
        ESP_LOGW(TAG, "Failed to start USB RNDIS driver, try again...");
        vTaskDelay(1000 / portTICK_PERIOD_MS);
        continue;
    }
    break;
}

Thank you for your feedback. We are modifying the driver to support deinit and interaction with AT commands. In addition, can you provide the crash log information you encountered?
