ASUS M5A97 LE R2.0 - How to power off USB when computer is shut down?

[Bigfool]

In BIOS v. 1903 (07/11/2013) I cannot see how to power on/off USB ports when computer is shut down. There is an "EPU" but no possibilities there. I want that the USB ports are unpowered when PC is shut down.I have read about "Erp" enabled/disabled in other threads but I find no such function in BIOS.
Looking very much forward to receive an useable tip/trick/idea - Thanks

I found the solution: Google for "Ai Suite 3", download and install in Windows. Reboot and go into BIOS - Now the "ErP" appears and you are able to enable this feature - I'm happy again
