I just received my DirectIn Response boxes. When I plug them in, the Mac immediately asks about this new keyboard that it cannot identify (seems to be going through the system preferences "Keyboard & Mouse" item). When you continue on, it asks you to press the key immediately to the right of the left shift key (which you of course can't do). Two choices now:
1) If you ignore what is happening, the response box does produce 1-9 as appropriate in all software - except where I need it most - using Psychophysics Toolbox's "KbName" command within Matlab.
2) If you continue on with the "Keyboard & Mouse" item, then you can choose a Japanese, U.S., or European - none result in behavior different than #1 above.

Any help?
