Hi, because my z68xp-ud3 sometimes wakes up and some others don't, I tried different things to solve this. One of this was to disable XHCI and EHCI hand-off. After that system boot faster and is also faster in Cinebench than before. It also wakes up but is too soon to say that will always wake.
Why people say that XHCI and EHCI hand-off should be enable?

After a week like this my system failed only once to wake up from sleep. Much better than before (with xhci snd ehci enabled).

Because you need it for booting from usb flash or external harddisk. After kernel load usb drives are getting shut off without Hand-Off enabled. At least on my Z97 platform.
