We’ve been utilizing USB connectors for 3 many years now—but many individuals don’t even notice there’s a Sort-B connector. For many, there’s the older, rectangular USB-A connector, the fashionable, petite USB-C connector, and some micro-USB connectors in between. I do know of us who assume the square-ish, chunky, beveled connector hiding behind their printer or connecting their audio gear is definitely a proprietary connector. However guess what—that’s really a USB Sort-B connector—and right here’s why this forgotten center little one of tech remains to be important.
Why folks forgot USB Sort-B
Many of us don’t even comprehend it exists
USB Sort-B was by no means really mainstream, so calling it “forgotten” could be beneficiant. Once I point out USB-B to folks, I’m normally met with confusion—virtually as if it isn’t actual. They assume that USB-B is like Windows 9 or iOS 19—the businesses simply determined to skip a era.
And the confusion is sensible. When was the final time you really noticed a USB-B port?
Wired keyboards, mice, and audio system usually shipped with fastened cables ending in USB-A, relatively than utilizing removable Sort-B ports. USB Sort-B was—and nonetheless is—reserved for bigger stationary peripherals that require detachable cables. From the start, it occupied a slim area of interest.
On high of that, you not often plug and unplug these gadgets. My Epson printer and Snowball iCE microphone use USB Sort-B, and I couldn’t let you know the final time I disconnected both cable. That lack of interplay makes the connector much more obscure—usually missed by individuals who already personal gadgets that use it.

USB Sort-B wasn’t actually the ‘sequel’ to Sort-A
Let’s break this widespread false impression
Wanting on the naming scheme—USB Sort-A, Sort-B, and Sort-C laid out alphabetically—it’s simple to imagine they signify generational upgrades. However that isn’t the way it labored.
The USB Sort-A and Sort-B connectors had been introduced together in 1996. They had been actually the 2 ends of the identical USB cable. Sort-C arrived a lot later, in August 2014, making it the youthful and extra fashionable sibling. However Sort-A and Sort-B had been extra like twins than sequels.
However Sort-C wasn’t paired with a Sort-D—so, why did Sort-A and Sort-B have to return in pairs? The reply comes right down to energy supply and gadget roles. USB was designed round a bunch–gadget structure, the place energy and information movement from the host (like a pc) to the peripheral (like a printer). If each ends used the identical connector, folks might by chance join two hosts collectively, inflicting energy conflicts or damaging {hardware}.
To stop that, the connectors had been bodily totally different. USB Sort-A was designed because the host finish—a flat, rectangular connector that plugs into a pc or energy supply. Sort-B was the gadget finish—a sq., virtually D-shaped connector that plugs into peripherals like printers, scanners, and audio interfaces. By making the connectors incompatible with one another’s ports, it eradicated the opportunity of plugging the flawed finish into the flawed gadget.
USB-C is taking on—so, what occurs to Sort-B?
USB-C can do alone what Sort-A and Sort-B did collectively
USB Sort-C was launched as the fashionable successor to the older Sort-A and Sort-B connectors. It essentially solved the limitation that made the Sort-A and Sort-B pairing needed within the first place. Sort-C helps USB Power Delivery, which permits related gadgets to dynamically negotiate and resolve which one provides energy and which one receives it. As such, you may plug it in both means—it doesn’t matter.
Past energy supply, the connector itself is symmetrical, which means there’s no flawed orientation. You plug it in both means, and it matches. Future generations won’t ever perceive the frustration of flipping a Sort-A connector a number of instances earlier than it lastly goes in. It’s additionally compact, making it excellent for contemporary {hardware} that retains getting thinner—telephones, laptops, tablets, even screens.
Evidently in virtually each measurable means, USB Sort-C is the superior connector. Even Apple—lengthy proof against industry-wide requirements—finally transitioned its iPhones and Macs to Type-C. In truth, on the time of writing, Sort-A is step by step disappearing from many new gadgets, changed by Sort-C ports and cables. So, in a world the place Sort-C is consuming the whole lot—how does Sort-B nonetheless have a spot?
It’s time for USB-A to die: Why my next PC will be USB-C only
Step apart grandpa, it is time for the youthful era to take heart stage.
Why USB Sort-B will proceed to thrive within the period of Sort-C
From a technical standpoint, USB-C can assist all the info protocols dealt with by USB-B, together with newer requirements and better energy supply ranges. Most often, USB-C is totally able to changing Sort-B. Nonetheless, connector selection isn’t decided solely by electrical functionality.
Sort-B’s bigger, keyed housing supplies a safe and predictable friction match. It feels stable and secure as soon as related. Additionally, its asymmetrical, beveled form makes the proper orientation apparent—avoiding the trial-and-error frustration we all faced with USB Type-A.
Moreover, Sort-B is widespread in industries the place bigger gadgets are the norm. Printers, business gear, {and professional} audio gear usually have ample inside area, making a bigger, extra strong connector sensible—and generally preferable.
Longevity performs a serious position as nicely. Merchandise like high-end audio interfaces and business printers can stay in energetic use for a decade or extra. Redesigning {hardware} to undertake a brand new connector includes engineering revisions, compliance testing, retooling, and manufacturing prices. Contemplating that the prevailing connector already meets folks’s expectations for reliability and efficiency, there’s little incentive to alter it.
What Is “Planned Obsolescence,” and How Does It Affect My Devices?
Corporations usually have a plan to make your devices out of date, even earlier than they’re manufactured.
While you view the dialogue from this attitude, swiftly, USB-C stands out as merely the “fashionable” various to USB-B—not essentially the “higher” various. And since most producers want stability and backward compatibility over modernization for its personal sake, it’s probably that USB Sort-B will preserve its relevance nicely into the foreseeable future—whilst USB-A begins to fade away.
