USB versions and types


In the way we save, transfer, and consume data, USBs continue to be crucial. But are you aware of the variations in USB types? What USB version are you using, exactly?

Here is all the information you needs to know about USBs in light of the recent announcement that the EU Parliament has agreed to implement a universal USB charging cable by the year 2024.

Version v of USB types

A USB type is the design of the connector, but a USB version is the technology implemented in the device that enables data transfer. The speed at which data base can be sent depends on the USB version.

USB device types

Since the late 1990s, USBs have proliferated in the workplace. But these little, reasonably priced gadgets are utilised almost every day as businesses and homes rely more and more on technology.

It can be difficulties to sort through a tangle of electronic cords to determine which type you actually need.


The most popular USB type is Type-A. The common, all-purpose connector found on almost every PC and laptop is Type-A. Type-A connectors are commonly seen on TVs, gaming consoles, and even some media players.


Many devices, like external hard drives and printers, demand a USB Type-B connection. The Type-B connector comes in two different configurations, which further complicates matters. Some employ the older USB 3.0 and later spec connections, while others use the faster USB 1.1 and 2.0 speed protocols.

USB Type-B

Type Mini-B ports are commonly found on portable devices including digital cameras, music players, and some mobile phones.

Micro-B USB

Micro-B connectors are frequently found on Android devices and external hard drives and are used in conjunction with USB version 2.0.


USB-C cables are becoming widely available as we utilise more and more handheld portable devices. The key advantages of Type-C cables are that they are more mobile-friendly due to being lighter and thinner than their predecessors.

Type-C connections, which may be used for charging and data transfer, are being incorporated into an increasing number of devices.

USB versions

Despite also being referred to as “Full Speed” USB, the USB 1 version’s top speed is only 12Mbps. While these older devices continue to function with modern modems, the speed in megabits per second won’t grow.

USB 2 – The USB 2 is a “High Speed” version of the USB 1. 480 Mbps as the maximum transfer speed available to users. Both modern and vintage devices continue to function with USB 2 versions.

USB 3 – This “Super Speed” USB version has a 5Gbps maximum transfer speed.

There are generational versions inside each USB version, such as USB 3.1, 3.2, etc., and each generation delivers more performance than the last.
