用USB CDC 4G Module时，卡在了Modem state STAGE_WAIT_IP步骤 (AEGHB-586)

Answers checklist.

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

General issue report

我的硬件是ESP32-S2连接EC600M-CN模块，直接用了USB_CDC_MODULE中的例程。IDF版本 5.1.2。开机log如下：

======================================================== 目前已经检查过EC600M模块，是正常工作的，SIM卡也可以注册上网，但就是无法获取IP。请大家指教是什么原因造成的？谢谢！
