Some devices put out a narrow (10 microsecond) pulse. I don't know
what the Oncore does.
I have one PC that works fine with a narrow pulse and another PC
that doesn't see it. I kludged together a pulse stretcher (diode, R, C)
and it started working. Well, I thought it was working. It turns out
that it only sees some of the pulses.
