Can You Connect One USB-C Hub to Another? Daisy-Chaining Hubs Safely

You already have a USB-C hub connected to your laptop, but you still need more ports. Can you plug a second hub into the first one?

In many cases, yes. A second hub can work when it is connected to a real USB data port on the first hub.

However, adding another hub does not create a second independent connection to the laptop. Both hubs still share the original USB connection, available bandwidth, and—in many setups—available power.

That makes hub-to-hub connections suitable for keyboards, mice, USB receivers, printers, and basic flash drives. They are less reliable for external SSDs, hard drives, webcams, cameras, capture cards, or additional displays.

Quick Answer

You can connect one USB hub to another for basic USB data devices.

For the safest setup:

• Connect the second hub to a USB data port, not a PD charging port.
• Keep high-power and high-speed devices on the primary hub or laptop.
• Use a powered second hub when several devices need power.
• Do not expect HDMI or laptop charging to pass through every hub layer.
• Use one docking station instead of multiple hubs for a permanent workstation.

What Happens When You Connect Two Hubs?

The connection looks like this:

Laptop → Primary USB-C hub → Secondary USB hub → Devices

The second hub adds physical ports, but all connected devices still communicate through the primary hub’s connection to the laptop.

For example, if the first hub has a 5Gbps upstream connection, the second hub does not receive an extra 5Gbps link. Its devices share the same bandwidth with everything connected to the first hub.

This usually does not matter for:

• Keyboard
• Mouse
• Wireless receiver
• Printer
• Security key

But it can matter when several high-speed devices are active at the same time.

For example:

• External SSD
• Webcam
• Capture card
• Camera
• Large file transfer

A second hub adds ports—not additional bandwidth.

Which Devices Are Best for the Second Hub?

The secondary hub is best used for low-power, low-bandwidth accessories.

Usually suitable

• Keyboard
• Mouse
• USB receiver
• Printer with its own power supply
• Game controller
• USB security key
• Basic flash drive

Better connected directly

• Portable SSD
• External hard drive
• Webcam
• USB microphone
• Audio interface
• Capture card
• Camera
• Phone
• Optical drive

For important file transfers, connect external storage directly to the laptop or primary hub whenever possible.

A compact USB hub for keyboard and mouse is usually enough when the main goal is simply adding ports for basic accessories.

Both Hubs Share Bandwidth

USB hub bandwidth is shared between connected devices.

Consider this setup:

Laptop
  │
Primary USB-C hub
  ├── External SSD
  ├── Webcam
  └── Secondary hub
      ├── Keyboard
      ├── Mouse
      └── Flash drive

The keyboard and mouse use very little bandwidth, so they should work normally.

However, if the SSD is transferring large files while the webcam is active, performance may drop because all devices share the original upstream connection.

A faster secondary hub will not make a slower primary hub faster. The entire chain is limited by the slowest connection in the path.

Power Can Become the Bigger Problem

Two bus-powered hubs may rely on the laptop for:

• Primary hub operation
• Secondary hub operation
• USB devices
• Storage drives
• Phones
• Cameras
• Status lights and internal controllers

The setup may work with a keyboard and mouse but become unstable after adding a portable hard drive or webcam.

Common signs of insufficient power include:

• Drives disconnecting
• Webcam freezing
• Devices appearing and disappearing
• Slow phone charging
• USB power warnings
• Interrupted file transfers

When several devices need power, a powered USB hub for multiple devices is safer than chaining two small bus-powered hubs.

A powered hub uses its own approved adapter to supply power to downstream USB devices. It can improve stability, although it does not increase the available data bandwidth.

Can You Connect Chargers to Both Hubs?

Usually, you should not connect chargers randomly to both hubs.

A USB-C port labeled PD or Power Delivery is often a charging input for the hub connected directly to the laptop. It may not be a USB data port.

Recommended arrangement:

1. Connect the laptop charger to the primary hub’s PD port.
2. Connect the secondary hub through a USB data port.
3. Do not connect a second PD charger unless the manufacturer explicitly supports that setup.
4. Do not expect two chargers to combine their wattage.

A self-powered USB hub with its own dedicated AC adapter is different. Use the supplied adapter according to the product instructions, but do not treat it as another laptop charger.

Will HDMI Work on the Second Hub?

Usually not.

A hub’s HDMI port needs a video signal from the laptop. That signal may use DisplayPort Alt Mode, Thunderbolt, USB4, or another supported display technology.

Most downstream USB ports on a hub carry USB data only. They do not pass a new video signal to another hub.

This setup usually works:

Laptop → Primary hub HDMI → Monitor

This setup often does not:

Laptop → Primary hub USB data port → Second hub HDMI → Monitor

If you need an external display, use the HDMI or video output on the primary hub, connect the monitor directly to another video-capable laptop port, or use a docking station designed for display output.

Do not assume that a USB-C-shaped downstream port supports video. It may support data only.

How to Test Two Hubs Safely

Do not connect everything at once.

Step 1

Connect the primary hub to the laptop and confirm that it works.

Step 2

Connect the second hub to a USB data port with no devices attached.

Step 3

Add low-power devices first:

1. Keyboard
2. Mouse
3. USB receiver
4. Printer
5. Flash drive

Step 4

Add higher-power devices one at a time:

• SSD
• Hard drive
• Webcam
• Camera
• Audio interface
• Phone

Step 5

Run a real test:

• Transfer files
• Join a video call
• Play audio
• Put the laptop to sleep and wake it
• Check laptop charging

Stop using the chain if devices disconnect repeatedly, become unusually slow, or interrupt file transfers.

When One Dock Is Better Than Two Hubs

Daisy-chaining hubs is useful for a temporary port shortage. It is less suitable for a full-time desk setup.

A single USB-C docking station for desk setup is usually better when you need:

• Monitor output
• Ethernet
• Audio
• SD and microSD
• Laptop charging
• Several USB devices
• External storage

Using one dock reduces cable clutter, simplifies power management, and makes troubleshooting easier.

For only keyboards, mice, and receivers, a small USB hub may be enough.

For several USB devices needing stable power, use a powered USB hub.

For displays, charging, Ethernet, audio, and storage, use one docking station rather than stacking several hubs.

FAQ

Can I plug a USB-C hub into another USB-C hub?

Yes, if the second hub connects to a USB data port on the first hub. Do not plug it into a PD charging-input port.

Will both hubs run at full speed?

No. Devices on both hubs share the primary hub’s upstream connection.

Can I connect an SSD to the second hub?

It may work, but a direct connection to the laptop or primary hub is usually faster and more reliable.

Can I use chargers on both hubs?

Only if the manufacturers explicitly support that arrangement. Two chargers do not automatically combine their power.

Will HDMI work on the second hub?

Usually not. The first hub’s downstream port must explicitly support video output, not only USB data.

Does a powered hub increase speed?

No. It improves available power and device stability, but bandwidth is still shared.

Is a docking station better?

For a permanent workstation with a monitor, Ethernet, charging, storage, and multiple devices, one docking station is usually the cleaner option.

Final Thoughts

You can connect one USB-C hub to another, but the second hub only adds more physical ports.

Both hubs still share:

• The original USB bandwidth
• Host-controller resources
• Available power in bus-powered setups

Use the second hub mainly for keyboards, mice, receivers, printers, and basic flash drives.

Keep external storage, webcams, cameras, and other critical devices connected directly to the laptop or primary hub. When several devices need power, use a powered USB hub for multiple devices.

For a permanent setup with displays, Ethernet, audio, storage, and charging, a single USB-C docking station for desk setup is usually safer and easier to manage than stacking multiple hubs.
