USB Power after shutdown

[Darxide]

I've just bought a logitech G15 gaming keyboard, and a Roccat Kone gaming mouse.
Problem is, when I shut down the PC, the lights on the KB and Mouse stay on.
And if you know this KB, you'll know what I mean :-0

Is there usually an option in BIOS to turn off USB power after shut down?
I can't seem to find anything.

M/B as in my sig.

Thanks.

It could come under the power state options in the BIOS (S1 and S3 I think they are). Try changing between them and see how you go.
