[Chugalug] force usb enumeration?

I'm not sure wtf is going on with it. I just repartitioned it and
reformatted as ext3 thinking it may just be ntfs screwing with it. That
cleared up the weird uuid, so I put that in fstab and tried again. Ubuntu
still prompts me at boot to "Press S to skip" for the missing disk at boot.
The system goes to sleep after there's no activity. As soon as I replug it,
it was mounted on /usbhd :

Is it possible the drive is going to sleep? Does the drive power via USB?
If not, does power off/on accomplish the same thing?
