This is really odd, because I have two Yosemite machines that work
fine with your posted code. I’m trying to figure which of my Macs I
want to subject to the ElCap upgrade, and will test on that and report.

For fun, have you tried the other non-hid keyboard device example?
This one suffers from not working on Windows, but uses a non-hid
path without requiring device number, etc.

// computer keyboard input via terminal
KBHit kb;

// time-loop
while( true )
{
  // wait on event
  kb => now;

  // loop through 1 or more keys
  while( kb.more() )
  {
    // get and print key...
    kb.getchar() => int c;
    <<< "ascii:", c >>>;
  }
}
