My screenshot is made on 1903, all the powerschemes have the option to set it to never (i've checked). I have something like yours, no drivers needed.
I never noticed that ASMedia link that appeared in the quote, since it's not on the original post. Odd. However, I heard back from the company and they said they think it might be defective and will send me a new one under warranty, so it's nice that they stand by their products.
