Introduction

I went at the ECW 2022 and in all the goodies I got, there was this tiny amossys USB hub

This got me interested since there are some USB devices that I would like to test on their USB port or cable but since I don’t want to cut the cables or damage the USB connector haven’t tried yet

Let’s take a look at the device

Here is a small collage of the device and under several angles

Building phase

Device tear down

Let’s open it to see if there are any copper lines or cables between the ports and also make sur all the female ports are linked to the male one (that’s my default assumption regarding the device from outsite)

Wireing

As we can see in the above right pic (circled in red) are the connectors of each USB ports that are used to reciew devices.

I decided to probe the 4 ports and cutted down 4 colors or cable (one for each port)

Color layout :
Black : GND
Orange : +5V
Green : DATA +
Purple : DATA -

Final look

Once every cables are installed in the plastic cover, time for some soldering and then, we have a nice USB test bench to try different devices
