Mouse still on after shutdown of MA790GP-UD4H

I just put in a Gigabyte MA790GP-UD4H motherboard. Everything looks to be working except it won't shutdown. I saw a FAQ on Gigabytes website that says this is a feature

"This is Gigabyte design spec, allows rechargeable mouse or cell phone can still be charged even the PC is turned off. 2. This also allows PC to wake up by USB or PS2 mouse and keyboard, without further setting of jumper on the motherboard. 3. Users can use some optical mouse which has power management feature, the LED can be turned off when PC is at off state, or remove the AC power cord. "
