USB hubs for laptops and desktop computers

A USB hub expands a single computer port into several additional connections.

It is particularly useful for laptops with a limited number of built-in USB ports, but it can also make desktop computer ports easier to access.

The current category contains five products, mainly compact 4-port models and a larger 7-port USB 2.0 hub.

What is a USB hub used for?

A USB hub allows several compatible devices to share one computer USB connection.

Examples include:

• mice;
• keyboards;
• flash drives;
• memory-card readers;
• printers;
• wireless receivers;
• controllers;
• selected external drives;
• other USB accessories.

Simultaneous operation also depends on the power requirements of the connected equipment.

4-port USB hubs

Most products in the current range provide four additional ports.

This is a practical size for everyday desk use and provides enough connections for several standard peripherals without requiring a large docking station.

USB 3.0 hubs

The category includes USB 3.0 models.

One verified hub provides data transfer of up to 5 Gb/s through its USB 3.0 connection, while additional ports may operate at USB 2.0 speeds of up to 480 Mbps.

USB 3.0 is particularly useful when transferring larger files with compatible storage devices.

USB 3.0 versus USB 2.0

The main difference is maximum theoretical transfer speed.

USB 2.0 supports up to approximately 480 Mbps, while USB 3.0 can reach approximately 5 Gb/s with compatible hardware.

Actual performance depends on:

• the computer port;
• the hub;
• the connected device;
• the storage medium;
• the type of data being transferred.

Mixed USB-port hubs

Not every product labelled as a USB 3.0 hub necessarily uses USB 3.0 on every port.

One verified model combines a USB 3.0 port with three USB 2.0 connections.

Always check the specification of individual ports.

7-port USB hubs

A 7-port USB 2.0 model is also available.

The additional ports may be convenient at workstations using multiple low-power peripherals at the same time.

Bus-powered USB hubs

One verified 4-port model does not require a separate power adapter.

It receives power directly from the computer USB port.

This reduces the number of cables but also means that available power is limited by the computer connection.

When is a powered hub preferable?

Several higher-power devices may require more energy than a simple bus-powered hub can supply.

If connected equipment behaves unpredictably, check device power requirements and consider a separately powered USB hub where appropriate.

USB hubs for laptops

Many laptops provide only a few standard USB connections.

A compact hub allows a mouse, keyboard, flash drive and other accessories to remain connected through one computer port.

USB hubs for desktop PCs

A hub can also bring computer ports closer to the user.

This can be useful when the desktop case is positioned under a desk or when rear ports are difficult to reach.

Hubs for mice and keyboards

Mice and keyboards generally do not require very high data-transfer speeds.

They can therefore be connected to USB 2.0 ports, leaving faster USB 3.0 connections available for storage devices.

Hubs for flash drives and external storage

Data-transfer speed matters more with storage devices.

When the computer, hub and storage device all support USB 3.0, higher transfer speeds are possible than with USB 2.0.

A hub cannot make the storage device itself faster than its own capabilities.

Up to 5 Gb/s data transfer

One available 4-port model provides a declared maximum transfer rate of up to 5 Gb/s on its USB 3.0 connection.

This is a theoretical maximum and real-world performance may be lower.

Operating-system compatibility

One verified product supports popular systems including Windows 11, Windows 10, Windows 8, Windows 7, macOS and Linux.

Simple USB hubs are normally detected automatically by the operating system.

Plug and Play

USB hubs generally require very little configuration.

Connect the hub to the computer and then attach compatible devices to its ports.

Compact dimensions

A verified compact model measures approximately 85 × 16 × 8.5 mm and has a cable approximately 9 cm long.

This makes it easy to store with a laptop and other travel accessories.

Cable length

A short cable keeps the hub compact and is convenient for laptop use.

For a desktop computer with ports located farther away, a longer cable may sometimes be preferable.

USB hubs for travel

A small hub is useful when travelling with a laptop that has limited connectivity.

It provides additional ports while taking up relatively little space in a laptop bag.

USB hubs for office work

At a permanent desk, a hub can reduce repeated cable swapping.

Several peripherals can remain connected to the hub, while the laptop connects through a single cable.

Does a USB hub increase available power?

No.

A bus-powered hub distributes the power available from the existing computer USB port between connected devices.

It does not create additional power.

Can all devices operate simultaneously?

A hub provides physical connections for several devices, but simultaneous operation depends on their power and data requirements.

Mice, keyboards and wireless receivers generally have modest requirements, while several storage devices may require more resources.

How to connect a USB hub

Connect the hub to a suitable computer USB port first.

Then attach devices one at a time.

Check that:

• the plug is fully inserted;
• the operating system detects the device;
• the correct port is being used;
• the connected accessory operates reliably.

Caring for a USB hub

Protect the hub from moisture and mechanical damage.

Regularly inspect:

• the cable;
• USB plug;
• ports;
• housing;
• any loose connections.

Disconnect the hub before cleaning its ports.

USB hubs and internet speed

A USB hub does not directly increase internet speed.

If a USB Wi-Fi or Ethernet adapter is connected through the hub, its performance depends on the hub standard, adapter and network connection.

Is USB 3.0 worth choosing?

USB 3.0 is useful when connecting devices that can take advantage of higher data-transfer speeds, such as compatible flash drives and external storage.

For basic peripherals such as keyboards and mice, USB 2.0 may be sufficient.

How to choose a USB hub

Consider how many devices need to be connected and what those devices require.

Compare:

• port count;
• USB standard;
• data-transfer speed;
• cable length;
• power method;
• compatibility;
• dimensions;
• housing design.

USB 3.0 support is particularly important when faster file transfers are required.

What should you check before buying?

Make sure the hub matches your equipment.

Check:

• computer port compatibility;
• required number of ports;
• which ports support USB 3.0;
• power requirements;
• cable length;
• physical dimensions.

The current range includes compact four-port hubs as well as a larger seven-port model.
