Please confirm whether this 4G module supports the PPPoS communication method, and try testing whether the bulk IN and OUT endpoints on the same interface can communicate.

@Rou-sir I have the same problem with ESP32S3 and ML307A. Could you share me your sdkconfig file?

I have updated the relevant code for this example. Please try using the latest version. Note that the new version no longer requires specifying the USB port number; you only need to configure the correct interface number.

Test with the latest code. Can modifying the interface number make the 4G module work properly?
