However, they’re still backward compatible and those faster speeds will only work when two USB 3.0 devices are connected to each other. Type-A connectors that support USB 3.0 speeds-the ones that often have blue on the inside-have nine pins versus the four pins found in older USB connectors. The same goes for ports: USB 3.0 ports often have blue on the inside and USB 2.0 ports often have black on the inside. Type-A connectors that only support slower USB 2.0 or USB 1.1 speeds often (but not always) have black on the inside. USB Type-A connectors and ports that support faster USB 3.0 speeds often (but not always) have blue on the inside. Blue USB Connectors Are Often Faster The blue inside this USB Type-A connector indicates it supports USB 3.0 speeds (probably.) LDprod/ In other words, you can plug any USB Type-A plug into any USB Type-A port and it will “just work.” If the devices are different generations-if you plug a 20-year-old USB drive into a modern PC, for example-they may perform slower, but they will work.
It will work at slower speeds, but that same USB Type-A connector lets you plug your device into almost anything. However, if you have a USB 3 device, you can still use that same USB cable to connect it to an old computer that only supports USB 2.0 or USB 1.1. if you have a modern computer that supports USB 3 and a modern USB device that supports USB 3, you can connect them with a USB cable that supports USB 3 speeds and get all the speed advantages. This longtime standard physical connection aids USB in backward compatibility. However, while Type-A connectors have been around for a while, they still work with the latest modern versions of USB. USB Type-A connectors date back to the the original release of USB 1.0 in 1996, although USB only really became common with USB 1.1 in 1998.

When it comes to the Universal Serial Bus (USB) standard, there are two things to think about: Physical connector shape and the underlying protocol (speed.) USB Type-A and Backward Compatibility Studio ART/ USB Type-A ports work with all USB versions, from USB 1.1 and USB 1.0 to USB 3.0, USB 3.1, and USB 3.2. These USB Type-A ports are also called receptacles.ĭevices like USB flash drives, mice, keyboards, external hard drives, webcams, digital cameras, game controllers, mobile devices, and numerous other peripheral devices and accessories often have USB Type-A connectors (often called plugs), which can be plugged into Type-A ports. You’ll find USB Type-A ports in most modern computers, laptops, game consoles (like the PlayStation, Xbox, and Nintendo Switch), smart TVs, streaming media players, and other devices. USB Type-A connectors are the most common type of USB connection you’ll find. What Type-A Connectors Are For A USB Type-A port, or receptacle.
