[HELP] Asus Rampage IV Extreme. USB still ON after shut down

Hi guys.
I'm just purchase an ASUS Rampage IV Extreme.
I Have some question here.

USB power still ON, even when computer is shut down.

may be someone tell me this: "why don't you just cut off the PSU switch button? or directly cut off the head power outlet?"
I DO. but it's still very annoying. come on, this is an era of instant right. this not an era of IBM PC pentium I, pentium II, pentium III or some other old stuff.

I know this is may be the smart feature to charge your mobile device like iPhone or iPod, even when the computer is OFF. but this is really annoying for me, cause I have so many USB Devices like external HDD, USB Modem, external USB fan. etc. and It's not funny to see my USB Devices still working (ON) even the computer is OFF.
at least tell me how to turn off that feature?

I've see the FAQ on ASUS website, and not found anything about my problem.

I've already update the latest BIOS, but still same problem.

I've try to setting all feature on the ACPI Configuration. disable all setting like power on keyboard, power on mouse etc. and still nothing.

can anyone help me?
I hope it's any ASUS guy here where can explain this problem,
at least tell me how to turn off the USB power when the system is off?

Please help me, if any way to solve this preblem.
Thanks in Advance.

Yes - that depends on how the PSU suports ErP. Not all PSUs turn power off to 5V.

I have the same issues, my qpad mk-85 lights will stay on after shutdown, and mice steelseries sensei. I have corsair ax1200 and ErP is enabled, never had this issue before.

I dont have that issue on my board/PSU.

ErP will disable if you use AI Suite and set Ai Charger enabled for standby charging..
