When connecting the LTE USB Dongle to openwrt, it is disconnected and reconnected after 10 seconds as below log.
However, even after connecting, the modem is not detected.
The dongle's model name is Alcatel IK41.
It does works on mbim mode.
In this state, if you unplug the USB Dongle and then plug it in again, it will be detected normally.
I would like to detect it while connected without plugging again.
Please let me know how to solve this problem.

However, when openwrt is rebooted with the USB LTE Dongle plugged in, it is normally detected.
