Windows 7 can't sleep. 90% sure I know the cause but don't know fix.

Okay guys,

I have a new computer I built myself. When I first configured it, it had no problems sleeping, but then I added after, both an Internal USB hub extender, and a CD/DVD drive writer.

Since this install, I now can not sleep, the computer IMMEDIATELY wakes up when I try to sleep it. I have a feeling the culpret is the USB hub but I can't figure out how to fix it.

The hub itsself has no power management settings in control pannel for not waking up, and I changed the settings on everything else just in case.

Does anyone have any clue? Or is this just the cost for installing a USB hub extender...
