Disable USB power when the system is off

[Hexnovae]

So I bought a GA-Z97P-D3 motherboard, hooked it up and stuff and it runs smoothly. Now my problem is this: I have a bunch of USB devices that have lights in them, and when the system is powered down, I'd like those lights to go off. But they don't. So I have to flick a switch at the PSU for them to turn off, and that's annoying as I shouldn't have to. I looked for a setting in the BIOS already but to no avail. How do I disable the USB power when the system is off?

I don't think I have ever seen a mother board where you can turn off the USB's when you shut down the computer. The only thing I would say to do is get a power strip. Set it where it is easy to use.
