After playing with the drive for a while, I was unable to get it to actually read a disk. It is getting power because it spins for a moment after a disk is inserted, but it seems that nothing else is happening. I did actually solder a header onto the motherboard to do this, so I'm pretty sure this is a good connection I'm making.

I would like to see how to get ADB working! That would be cool. When I search Google for it, I only find some thread in this very forum which doesn't really say anything about how to actually do it.
