This USB-C gadget from hell brings back the worst part of USB-A

USB-C ports, I must occasionally admit, are somewhat confusing. Different standards, different charging speeds, different data and video options, proprietary labels like Thunderbolt, all on top of identical plugs – it can be a lot.

But one thing that USB-C ports had in mind was a solution to one of the biggest annoyances with USB-A – it is no longer possible to insert a USB cable in the “wrong” way, thanks to the symmetrical design of the plug .

Or at least that spring, to mechanical engineer Pim de Groot came up with a USB-C gadget from hell, which do behaves differently depending on which way your USB-C connector faces. And I hate it so much.

The device itself is quite simple: When the USB-C cable is connected in a way, a green LED lights up on the top of the device. Plug it in reverse, and the bottom LED will glow green, a vicious horror that glows in a sea of ​​black silicon.

What earthly science has given this horror? As de Groot explains, USB-C plugs are not complete symmetrical ̵

1; it is a set of connectors used only when connecting plugs such as a USB 2.0 device located only on one side of the plug. And when you connect a plug to be used in a USB 2.0 setting, you can apparently take advantage of it to create the Groots damn device above, which uses a pair of microcontrollers that each light up when they detect these connectors. (USB-C 3.0 connections are apparently immune to the trick, thankfully.)

Insert into the abyss.

Unfortunately, instead of seeing the Groots eldritch sealed monstrous as a warning, some developers want to take things even further by deliberately trying to build a USB-C cable that requires a “superposition” maneuver to connect. disconnect and reconnect it to different directions before success. For the sake of all that is good in this word, we can only hope that these efforts do not succeed.
