Answers checklist.

  • I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
  • I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
  • I have searched the issue tracker for a similar issue and not found a similar issue.

IDF version.

v5.3.1

Espressif SoC revision.

ESP32-S3 (N16R2)

Operating System used.

Windows

How did you build your project?

Command line with idf.py

If you are using Windows, please specify command line type.

CMD

Development Kit.

ESP32-S3-DevKitC-1

Power Supply used.

USB

What is the expected behavior?

It should work without crashing.

What is the actual behavior?

I just downloaded the latest master branch esp-iot-solution.zip, went to esp-iot-solution-master\examples\usb\host\usb_cdc_4g_module build the code for esp32s3, connect esp32s3 dev kit with a7672s devkit using usb cable and run it and I got the runtime error.

Please help.

Steps to reproduce.

  1. Download the latest master branch of esp-iot-solution
  2. Go to esp-iot-solution-master\examples\usb\host\usb_cdc_4g_module
  3. Open ESP-IDF v5.3.1 then do the following commands
  4. idf.py set-target esp32s3
  5. idf.py menuconfig (change board to A7600C1)
  6. idf.py build flash monitor

Please modify the value of CONFIG_MODEM_USB_ITF to another value, try again, and then post the printed USB descriptors.

Thanks!
And sorry for my mistake.
Changing CONFIG_MODEM_USB_ITF to 0x05 solved the issue.
