ESP32S3 as usb host, how to get device's PROD_STR

My ESP32S3 works as usb host, connected with a usb device. The device's information:

I want to get the iProduct string "Symbol Bar Code Scanner", how should I do?

I found a function declaration at "esp-idf-v5.1.1/components/esp_rom/include/esp32s3/rom/usb/usb_descriptor.h" :

Code: [Select all] [Expand/Collapse]

1. bool usb_get_descriptor(uint16_t type_index, uint16_t lang_id,
2.                         int32_t *len, uint8_t **data);

It seems that this function can meets my need, but it has no definition.

I try to add log out at "hub.c" as follows:

but only get problem unicode:

I've solved this problem.
Refer to "test_hid_basic.c", use "hid_host_get_device_info()" to get device's info.
