    Best case: Nothing. Worst case, you'll fry the USB drive if the
    adapter happens to wire a powered pin (on the PS2 side) to a pin not
    designed to receive voltage. I've never looked at the specs, but I
    wouldn't expect that this would be the case.

    The secret of the USB-->PS2 adapters is they don't have any circuitry,
    all they do is provide an alternate connector, it's the keyboard that
    actually contains the USB *and* PS2 circuitry, and any device not so
    equipped won't work at all.

    This means that although most keyboards will work, not all keyboards
    will work behind a USB-->PS2 adapter.
