duart28: new design ideas * added input buffers (LVC with Ioff feature) to prevent high current flow from powered-up target into powered-down FT2232D inputs; * added series resistors on outputs to limit current flow from powered-up adapter into powered-down Calypso target; * buffer IC changed from 74LVC125A to 74LVC541A.
