If you have a (or similar Android-based USB 4G stick/dongle), Linux often doesn’t auto-load the right driver. Here’s how to prepare the driver environment so the modem is recognized as a network interface (instead of just storage or ADB). 1. Identify the device Plug in your UFI stick and run:
sudo nano /etc/usb_modeswitch.d/05c6:9091 Content:
lsusb -t | grep -A 5 "Modem" Force load, for example:
Also check modes:
