I'm trying to use a trigger/button box device on our MRI scanner with my Macbook Pro Intel with the latest PTB. PsychHID recognizes the device as a keyboard, and when I press the keys or the trigger goes off, key presses correctly show up in the Matlab command window, but PsychHID does not recognize them. I just want to do KbWait(-1), but the events never trigger the KbWait. I try KbWait(1), which is the device number for the trigger, but that doesn't work either.
Any hints?
