I have a USB ethernet card that works well with Ubuntu 18.04. Now I need to find a way to turn it on and off with command.



I tried the command sudo ip l s dev enx00249b450d4d down (enx00249b450d4d is the name of the interface), but nothing changes.



I also installed net-tools and tried the command sudo ifconfig enx00249b450d4d down, but had no luck either.



I searched the internet but the information about Ubuntu 18 is still scarce. Any idea?
