No, I just have a simple 2.5" drive enclosure.  It's this one:


That's got a 44-pin female plug on it.  There's no need for a 40-pin
plug, since it's got a USB connector that you can plug directly into
an available slot.  It doesn't need any external power either, since
it can get that via the USB cable.  It's really just a 44-pin
connector on one side, and a USB port and blinkenlight on the other.
Oh, and a flimsy aluminum case you can put around the drive.

Thanks.  I stopped by the Apple Store today and confirmed that with
one of their "geniuses".

Yeah. :(  It sure would be nice if Linux would at least create a
device when I plug it in, though...
