The X1 has 2 USB ports - the USB 3 port works fine
The USB 2 port on the left side detects added devices but non of the attached devices will work (eg : keyboard, mouse, wireless adapter, etc)
The port has been working fine up to now - Is the port toast or is this a setting issue ?
The system is up to date with current patches and Lenovo System updates and BIOS

Which OS do you have?
I suggest You to flash a USB stick with some Linux distro (Ubuntu for example)
Then boot from stick and chose "Try Ubuntu",
when you start it you can try to connect some USB device on that "not working" USB port
and then You will know for sure if it's a hardware or a software problem.
