The wiring in the tutorial is all reversed, this is why the usb chip burnt !
Look at the schema vs the photo below, they don't correspond. On the schema you've wired a MALE connector to the HUZZAH32, so when we see it and wire our FEMALE OLIMEX ARM OCD H connector the result is that all is reversed

Please correct your tutorial.
For my case it still don't work, but the problem can be now from the probe: when the Adafruit burnt it may have damaged the probe also.
