Even as we’ve moved from USB 1 to USB 2 and on to modern USB 3 devices, that connector has stayed the same. *Please note that devices and hardware with USB 3.2 Gen 2x2 support will only start rolling out slowly.Įver plugged in a USB cable to find yourself unable to do so until you turn it over and try again? That nifty little connector is the USB Type A connector. What are the big changes in the newest Generation?Ī) Double throughput compared to previous generation – up to 20 Gbps.ī) Supports only the USB Type C Connector (Type A not supported by this standard). It should help you navigate the USB landscape much better: Here's a table that outlines the new naming schemes, along with their old names and maximum speeds. In fact, when you go out to buy a device even today, most people struggle to understand what speeds they can expect. The reasoning behind this bizarre naming might be sound from a technical standpoint, but the average user will struggle to grasp the differences between these standards. Furthermore, the standard previously known as USB 3.1 Gen 2 will now be renamed to USB 3.2 Gen 2.Īdding to the chaos, the specification that was thought to be simply called USB 3.2 will now be called, USB 3.2 Gen 2x2! The new standard offers twice the throughput that is offered by USB 3.2 Gen 2 (so, 2x2). Under this rebranding, the standard previously known as USB 3.0 or USB 3.1 Gen 1 will now be called USB 3.2 Gen 1. The USB-IF (USB Implementers Forum) announced the rebranding of both the USB 3.0 and USB 3.1 specifications in the last week of February 2019 (Yes, the déjà vu is real, it's happening again). The confusing naming schemes of newer and faster USB standards seem never-ending and the latest announcement will leave most people perplexed yet again. Their naming and specifications of USB revisions have been adopted by nearly all major IT companies around the world. Specifications and various technical details regarding each USB iteration are announced by the USB Implementers Forum, a group founded by seven major IT companies to support and promote the development of high-quality connectivity standards. As time passes, standards need to be updated to keep up with modern hardware and end-user requirements. Universal Serial Bus, or USB, has been around for a long time and we've used it to connect a wide variety of devices from storage to input hardware.
