How do I disable wakeup for the EHCI controllers? Also, does wakeup have anything to do with suspend. As the name suggests, it sounds like its more of a resume thing. But again, I'm ignorant when it comes to these matters.

Of course, vendors bend over backwards for MS, so it may not need to do much, or MS does something completely different. I do have this still as a dual boot with Windows7. I don't wipe my boxes clean of windows anymore. If I have to pay the damn MS tax, I might as well keep what I paid for :-p -- Steve
