The Jetson must be in recovery mode for it to show up, and the micro-B connector must be used. The supplied cable would be recommended.
Are you sure it was in recovery mode? Basically, anything that turns on power while the recovery button is held down should do this; from power off, hold down recovery, tap power; or with power on, hold down recovery, tap reset button. When this happens the Jetson becomes a programmable device on USB (instead of being a computer on its own). Do note that the wrong cable type will fail (either the full-sized connector or a type-A micro would fail…only micro-B works).
