    Looking at your code I see some strange "spaces" in the lines where you set the Conversion speed & Sampling speed.
    Is this also in your actual code? Do you get compiler warnings/errors?

    @Andreas,

    Thanks for the reset suggestion. My teensy 3.1 was also "dead" on the USB bus, connecting reset to GND while inserting the USB cable brought it back to life.
