How to disable individual USB ports by script?

I am looking for a script which will allow me to disable one specific USB port on my Mac mini. It would only serve a purpose if it works in real-time and didn't require a reboot. I've found scripts for various Linux distros that seemed to do something similar - however most required a reboot.

I've got ambient lighting behind my monitor which is powered by USB and it doesn't turn off when the system sleeps. So my office is constantly lit up, it would be nice if I could write a script that would disable that specific USB port.

Have you seen this thread and the code here? Maybe shell could be used to "manually" rename the device ID or port to something odd that won't work, upon a specified event, then renames it to what it's supposed to be later.
