Firewire: Don’t Plug It In Backwards!

Or you’ll find out why it’s called Firewire.

Firewire Hub Chip -- After

That’s the chip inside a former Firewire hub.

That’s a closeup of the destroyed pin. These images were taken with the QX5 toy microscope.

You’re lucky the web doesn’t have smell-o-vision yet.

  1. Yikes!

  2. I’ve not used FireWire. Did you plug the cable in backwards? Are the connectors poorly enough designed that you can do that? Ugh!

  3. The connector is designed to be keyed. It has a tombstone shape that should be impossible to plug in backwards. However, the usual implementation is sloppy and made of extremely thin sheet metal. With just a little force, it’s very possible to plug it in backwards.

    I am not certain that’s what I did, but it seems likely. I was rewiring things, working under the bench where I couldn’t really see what I was doing. There was a ty-wrap in the way and I might have applied excess force to push the ty-wrap aside.
