I have a ZTE Mobley device, and it worked well with ASUS stock firmware as a USB modem.
I now have a TP-Link Archer C7 v4 and installed OpenWrt 18.06.1.
Currently it does not show any option for USB.
I tried following some instructions online by installing packaged kmod-usb-*, they are installed but I still can't configure the USB connection. Maybe because I need to activate the packages, I don't know.
Could someone help me with some guidance? Am I supposed to do all that via SSH, or can be done via LuCI interface?
Thank you for any help!
