esp_modem example in ESP32-S3-DevKitC-1 v1.0

[thiagozf1]

I was trying to make the modem_console example (I don't know if this example is the best to what I want to do, that is basically send AT commands and data via USB to the BG95) to work with the ESP32-S3-DevKitC-1 v1.0 and the Quectel BG95 modem. My esp kept crashing until I modified the sdkconfig CONFIG_EXAMPLE_SERIAL_CONFIG_USB to "y". After this, the program runs fine until the initialization of esp_modem, when he keeps into an eternal loop searching for a usb device. I've tried connecting the modem via USB with the quectel LTE EVB kit and a pendrive (just to see if anything happens) but in neither situations something happened. This is what I get in the terminal:

Can someone provide me with some support?
Thanks, Thiago.
