I actually already tried plugging it into a different port and all of them are the same. They all give power in standby mode. But a correction they do not still give power when the computer is turned off.
Heres another thing.
In the devices and printers area if I right click on my unifying reciver or my headset, click on properties, click on the hardware tab, click on properties, then click on change setting, and click on the power management tab, the option that says "allow the computer to turn off this device to save power" is grayed out. This again is for the two device that show up there. I just wanna cut power to my chill pad when it goes into standby.
Thanks to everyone who has tried to help with this. I have done some searchin on google and I am not the only one with this problem. I will try to email the motherboard manufacturer and if they give me a solution I will post it on here. If anyone has any ideas, help is appreciated.

I have a ThinkPad W520 and ran into a similar issue.
Firstly, the ThinkPad has a BIOS option that toggles power to the USB ports based on system power state so you may want to check that.
Within Windows, I found I had to do two things; for each USB hub, I ticked "Allow the computer to turn off this device to save power", AND I had to go through every keyboard & mouse device an un-tick "Allow this device to wake the computer".
It seems Windows 7 is smart enough to maintain power to the USB hubs as long as there is a device connected that is allowed to wake from sleep. I should also mention that this is despite having "USB selective suspend setting" DISABLED. All very confusing but doing all of the above has made my USB ports power down in sleep/standby mode.
