So you have 2 USBC devices you want to connect together, a laptop and a phone for example, but for some reason you can’t find your USBC to USBC cable but you do have 2 USBC to USBA cables.
Well by breaking the USB specifications you can connect the 2 cables together to make a janky USBC to USBC cable.
Alternatively you can get single circuit boards with USBA ports on them and you can use this jank of an adaptor to link them together.
