Thanks Jon,
I’m no able to see any ttyUSB under /dev but I do see cdc-wdm0 and cdc-wdm1. If I try to use cdc-wdm0 , minicom says that the device is offline. I am however able to use the uqmi commands to get the signal info and data status.
The other issue I am having is to make the Gobi files as you had suggested. I believe OpenWRT cannot perform it. For the drivers I had gone through the thread below but seems like I do not have qmicli on my OpenWRT.
Sorry, I am a bit lost here right now. Thanks in advance for any help I can get.
