USB B, also known as USB Type B, is a type of USB connector that has been around since the inception of the USB standard. While it may not be as widely recognized as its more popular counterparts, USB A and USB C, USB B has its own set of unique uses and applications. In this article, we will delve into the world of USB B, exploring its history, design, and most importantly, its uses.
A Brief History of USB B
USB B was introduced in the late 1990s as part of the original USB standard. At the time, it was intended to be used as a connector for peripheral devices such as printers, scanners, and external hard drives. The USB B connector was designed to be a “square-shaped” connector, with a slightly larger size compared to the USB A connector. This design allowed for a more secure connection and better durability.
Over the years, USB B has undergone several revisions, with the most notable being the introduction of USB B Mini and USB B Micro. These smaller variants were designed to be used in applications where space was limited, such as in mobile phones and portable media players.
Design and Features of USB B
So, what makes USB B unique? Let’s take a closer look at its design and features.
USB B Connector Design
The USB B connector is designed to be a “host” connector, meaning it is typically used on devices that provide power and data to other devices. The connector has four pins, two for power and two for data. This design allows for a maximum data transfer rate of 480 Mbps, which was the standard speed for USB 2.0 devices.
USB B Variants
As mentioned earlier, there are several variants of the USB B connector, including:
- USB B Standard: The original USB B connector, designed for use in full-size peripheral devices.

Note: The table above provides a summary of the different USB B variants, their descriptions, and uses.
1. What is USB B and how is it different from USB A?
USB B is a type of USB connector that is typically used on devices such as printers, scanners, and external hard drives. Unlike USB A, which is usually used as a host connector on computers and other devices, USB B is used as a device connector. This means that it is used to connect devices to a host, rather than the other way around.
The main difference between USB B and USB A is the shape and size of the connector. USB B is typically smaller and more square-shaped than USB A, and it has a slightly different pin configuration. This means that a USB B connector will not fit into a USB A port, and vice versa.
2. What are the common uses of USB B?
USB B is commonly used to connect devices such as printers, scanners, and external hard drives to a computer or other host device. It is also used on some industrial control devices, medical equipment, and other specialized devices. In addition, USB B is sometimes used as a charging port on devices such as e-readers and other mobile devices.
The use of USB B as a standard connector for these types of devices has made it an ubiquitous feature on many types of electronic equipment. Its widespread adoption has made it easy for users to connect their devices to their computers or other hosts, and has helped to simplify the process of transferring data between devices.
3. Is USB B faster than USB A?
USB B has the same maximum data transfer speeds as USB A, with speeds of up to 480 Mbps for USB 2.0 or 10 Gbps for USB 3.2 Gen 2. However, the actual transfer speed will depend on the specific device and host being used, as well as the type of cable being used.
In general, USB B offers the same level of performance as USB A, and can be used for a wide range of applications, from data transfer to device charging. Whether you’re connecting a printer or an external hard drive, you can expect USB B to provide reliable and fast data transfer speeds.
4. Can I use a USB B connector to charge my devices?
While some devices use USB B as a charging port, it is not always the case. In general, USB B is not designed to be a high-current charging port, and may not be able to supply enough power to charge larger devices such as laptops or tablets.
However, some smaller devices such as e-readers or handheld game consoles may use USB B as a charging port, and may be able to charge from a standard USB host port or a wall adapter. It’s always a good idea to check the documentation for your specific device to see if it can be charged via USB B.
5. What is the difference between USB B and USB Mini B?
USB Mini B is a smaller version of the USB B connector, and is often used on smaller devices such as digital cameras and portable media players. While both USB B and USB Mini B have similar pin configurations, the Mini B connector is smaller and more compact.
The main difference between the two is the size and shape of the connector. USB Mini B is smaller and more rounded than standard USB B, and is often used in applications where space is limited. However, both connectors offer the same level of performance and functionality.
6. Can I use a USB B cable to connect multiple devices to a single host?
USB B cables are typically designed to connect a single device to a host, and may not be suitable for connecting multiple devices. If you need to connect multiple devices to a single host, you may need to use a USB hub or other device that can support multiple USB connections.
However, it is worth noting that some USB B cables may be specifically designed for daisy-chaining multiple devices together. These cables typically have multiple USB B connectors on the end, and can be used to connect multiple devices to a single host.
7. Is USB B still relevant in the age of USB C?
While USB C is becoming increasingly popular as a newer, faster, and more versatile connector, USB B is still widely used and remains relevant. Many devices, such as printers and scanners, still use USB B as a standard connector, and it is unlikely to be phased out any time soon.
In addition, USB B is often used in applications where reliability and durability are critical, such as industrial control systems and medical equipment. While USB C may offer faster speeds and more features, USB B remains a reliable and widely-used connector that will likely continue to be used for the foreseeable future.
