Thanks!
Now I have another question about the IOCommandGate.
Should I put all the IO request to runAction()?
When should I call commandSleep() and commandWakeup()?
When system goes to sleep, should I call commandSleep()?
When system goes to wakeup, should I call comandWakeup()?
But the system cannot be waken up if I use above methods.

I'd recommend you read this if you haven't already:
Do you call PMinit(), joinPMtree(), registerPowerDriver() in your driver? See "implementing basic power management" section in the IOKitFundamentals document.

Hello,
My driver (kext) is one USB driver.
Whey system goes to sleep, I plugout then plugin the USB device.
Then the system wakes up, but my driver cannot respond to any request, it seems that it is still in sleep mode.
I have registered a function handlePowerEvent to handle sleep.
But it only handles kIOMessageCanSystemSleep and kIOMessageSystemWillNotSleep, why is there no message type for Wake up?
