Turn off power to usb port mac
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. Another way of attacking the problem could be to add a USB hub to the system and connect the ambient lighting to that. That way you can control the lighting from a script. You will need to select a supported USB hub though. I used this method for controlling power under Linux - but the same method could also be used on Mac OS X.
The USB hub was very cheap. This is something controlled by the hardware layer of the OS and involves far more work than it's worth. While similar scripts exist for Linux, you must keep in mind that even though OS X and Linux are distant cousins, OS X wasn't built for such fine-grained control over its components like Linux was.
