The driver of 4G module is uninstalled

OS is Ubuntu 1804. The Huawei 4G module is ME909S-821a V2.
Huawei 4G module connects to Nano by USB port.
When the Jetson Nano system running for long time, the driver of the Huawei 4G module can be uninstalled.
Has anyone encountered similar problems? Thank you.

Hi, This topic will get better visibility in the Jetson Nano category. I have moved it over for you.

It’s the same as Issue of 4G module on Jetson Nano-Jetpack 4.5.1(L4T 32.5.1) - Jetson & Embedded Systems / Jetson Nano - NVIDIA Developer Forums
