All ports on this dongle are swapped. Upside down compared to MacBook and iMac connectors. I marked my cables with a dot, which means "this side up" for all my devices. That way I never risked damaging a connector or cable. In this key, each port is 180 degrees opposite. The best example is the SD card slot. On every computer or device I own, the label on the SD card is facing you. Either UP or FORWARD. Even my old Kodak camera has an SD connector, the label faces the user. On this button it is OFF or absent. Why? You will typically see the cable logo UP on a USB, Ethernet, FireWire, or Thunderbolt cable when properly installed. On this button, they all face down. Why? Yes the key is installed correctly on my new MacBookAir donkey. These are the ports of the dongle, these are facts.
