Eg916q-gl factory reset

I am using eg916q-gl module for lte connection for a embedded device. I tried to connect it with the ubuntu in my laptop. At first I was able to connect it by running quectel-CM in the linux pc. But I am not sure what I have done it led to automatic connection of the modem whenever i connect the pc with the quectel module.

Can someone explain what could have caused it?
How to reset the configuration or reset the module?

Hi,
Pls check your configuration with AT+QCFG=“usbnet” command.
if it is EMC,it will be auto connect.
