 If you're using another interface other than the ones [listed below](#compatible-interfaces), you need to add them to the udev rule manually
 
+First, get all USB devices connected to the computer and find your interface
 ```bash
-# Get all usb devices and find your interface
 $ lsusb

+Example for ID `1234:5678`
