Since I don't have the equipment to measure the power, I don't know for a fact if the device really has been put in a suspend state or not. Hello Franklin, Just to be clear, I'm not proposing that you remove the suspend logic. I was suggesting that you should be breaking the change into three separate patches, so that if a problem arises we can isolate whether it is a result of the power management changes. Having a separate patch is especially valuable because you are touching other drivers which are shared by other products. Cheers, Devin -- Devin J.
