    Brilliant, you're a genius. Well, maybe not since you just broke your
    scanner. But, what this means is that you can use the protocol that I have
    already worked out to support 630U (and 330U as well). All you need to do
    figure out how to use that GL640 chip. Hopefully it will be a simple
    encapsulating thing.

    Good luck, let me know if you get stuck and I'll help you as much as I can.

    I'll tear your mind out. I'll burn your soul.
    I'll turn you into me.
