What Exactly Is USB Type B?
The USB B connector is one of the original USB connector types. It has a distinctive square shape with slightly beveled corners. You will usually find it on the device end of a cable, while the USB A plug sits on the computer end.
USB Type B was designed to handle power and data for larger peripherals. Think printers, scanners, and external storage devices. Over the years, the USB B port has evolved through several versions:
- USB 2.0 Type B — the classic standard most people recognize
- USB 3.0 Type B — adds a blue insert and faster speeds
- USB 3.1 Type B — supports even higher data transfer rates
Each version is physically different, so you cannot plug a USB 2.0 cable into a USB 3.0 port by mistake. This design choice helped prevent damage and kept device compatibility straightforward for years.
The Shape That Stands Out
One reason USB B is so recognizable is its unique shape. Unlike the small, reversible USB C connector, the USB B plug is large and rectangular. This design was intentional. It made it easy to tell which cable went where, especially in busy office environments with dozens of devices plugged in.
The square shape also provided a secure fit. USB B cables do not wiggle loose easily, which matters a lot for devices like printers that stay in one place for years.
Where Is USB B Still Used Today?
You might be surprised by how many devices still rely on USB Type B connections. Despite the rise of USB C, the USB B port has not disappeared. Here are the places you will still find it.
Printers and Scanners
The most common use of USB B is in printers. Nearly every printer on the market uses a USB B port for the direct connection to a computer. The printer cable with the square plug is a staple in offices and homes worldwide.
Scanners follow the same pattern. Many flatbed scanners still ship with USB B cables because the connection is stable and reliable for large file transfers.
External Hard Drives and Storage
Many external hard drives and larger storage devices use USB B connectors. This is especially true for desktop-class drives that need more power than a standard USB A port can provide. The USB B connection delivers both stable data transfer and sufficient power.
Interestingly, when you buy an M.2 NVMe SSD USB enclosure, some models still include USB B outputs alongside USB C options. This gives users flexibility to connect older devices that only have USB B ports available.
Audio and Musical Equipment
Professional audio interfaces and digital mixers often use USB B connectors. Musicians and producers rely on these connections for low-latency audio transfer. The sturdy build of the USB B plug makes it ideal for equipment that gets moved around on stage but needs a dependable connection.
Industrial and Medical Devices
In factories and hospitals, USB B remains a go-to choice. Machines, monitoring equipment, and diagnostic tools frequently use USB Type B because the connectors are durable and well-understood by technicians. Switching to a new connector type would require costly retraining and equipment replacement.
USB B vs USB C: The Big Comparison
The tech world is shifting toward USB C, but that does not mean USB B has lost its value. Let us compare the two directly.
| Feature | USB Type B | USB Type C |
|---|---|---|
| Shape | Square, bulky | Small, oval, reversible |
| Common Devices | Printers, scanners, external drives | Phones, laptops, tablets |
| Speed (Max) | USB 3.1 Gen 2 (10 Gbps) | USB 3.2 Gen 2×2 (20 Gbps) |
| Power Delivery | Up to 5W (USB 2.0) | Up to 240W with USB PD |
| Reversible | No | Yes |
| Longevity | Still widely manufactured | Rapidly becoming the standard |
The table above shows that USB B still holds its own in certain areas. While USB C offers faster speeds and more power, USB Type B connectors are built for durability and long-term device connections.
If you are trying to connect an M.2 NVMe SSD to your laptop using an external enclosure, you might encounter both USB B and USB C options. Some enclosures come with USB B to USB A cables, while newer models use USB C. Understanding the difference helps you choose the right setup.
When to Choose USB B
You should stick with USB B when connecting devices that natively use it. Forcing a USB C adapter into the mix can sometimes cause issues with device compatibility and connection stability. If your printer works perfectly with a USB B cable, there is no need to change.
When USB C Makes More Sense
For modern laptops, phones, and tablets, USB C is the clear winner. It is smaller, reversible, and supports the latest USB standards. If you are buying new cables, USB C is the safer investment for the future.
Is USB B Becoming Obsolete?
This is the question on everyone’s mind. The short answer is: not yet. While USB C is growing fast, USB B still has a massive installed base. Millions of printers, scanners, and legacy devices around the world depend on the USB B port.
Manufacturers are slowly phasing out USB Type B on new consumer devices. However, in professional and industrial settings, the shift is happening much more slowly. A factory floor full of machines with USB B connections is not going to rip them out overnight.
Here are some reasons USB B is sticking around:
- Backward compatibility — older devices still need USB B cables
- Durability — the sturdy design lasts for years of daily use
- Power delivery — some devices need the power profile of USB B
- Cost — USB B cables are cheap and widely available
- No need to upgrade — if it works, why replace it?
That said, if you are shopping for new equipment, paying attention to USB B vs USB C support is smart. Devices that offer USB C alongside or instead of USB B are future-proofing your setup.
The Transition Timeline
Experts predict that USB B will remain in active use for at least another 5 to 10 years. The connector has a strong foothold in specific niches that USB C has not fully reached yet. Until those industries fully adopt USB C, USB Type B will continue to serve its purpose.
Common USB B Devices You Probably Own
You might already own several devices that use USB B without even realizing it. Here is a quick list of common gear:

If you have ever struggled with a USB B cable that only fits one way, you are not alone. The non-reversible design can be frustrating, but it also means you never have to worry about plugging it in wrong.
Quick Tip: Identifying USB B Cables
Not sure if you have a USB B cable? Look for the square-shaped plug on one end. It is wider than a USB C plug and has flat sides with slightly rounded corners. If you see a blue insert inside the USB port, it is a USB 3.0 Type B connection, which supports much faster speeds than USB 2.0 Type B.
What Does the Future Hold for USB B?
The writing is on the wall — USB C is the future. The USB Implementers Forum has been pushing USB C as the universal standard for years. New devices are increasingly shipping with USB C only, leaving USB B behind on the cutting edge.
But the future does not mean the end. USB Type B will likely follow the path of older connectors like serial and parallel ports. They will not vanish overnight. Instead, they will slowly fade as devices that need them are replaced.
For now, USB B remains a reliable and practical choice for many applications. Whether you are connecting a printer, an external drive, or professional audio gear, the USB B connector gets the job done.
If you are dealing with USB B connectivity issues, remember that a simple USB B adapter or replacement cable often solves the problem. Sometimes the issue is not the port itself but a worn-out cable or a driver conflict. Before assuming the worst, try a different USB B cable or test the device on another computer.
In summary, USB B is still very much alive and relevant. It might not be the flashiest connector on the market, but it serves a purpose that USB C has not fully taken over yet. Understanding USB Type B helps you make smarter buying decisions and troubleshoot connection problems with confidence.
