Asus P5Q Deluxe wake by USB keyboard

I have a Logitech USB keyboard, but I can't figure out how to get the bios to let me use it to wake up the computer. Seems to only work for PS2 devices.
Any thoughts?

Go into "Device Manager", then "USB" section, then double click EACH of the "USB Root Hub" device. Then select the "Power Management" tab and make sure that "Allow this device to bring the computer out of standby" IS checked. Also UN-CHECK the "Allow the computer to turn off this device to save power" option.

Hope this works.

Thanks. <"Allow the computer to turn off this device to save power" option>.
I tried that but they came back as checked as soon as I restarted.
Also the other box is greyed out.
Would having the EPU-6 engine activated cause this problem?

try enabling "Legacy USB Support" in the BIOS.
