You can daisy chain USB C hubs, but only under specific conditions, and it’s not always the best idea for your setup.
Before you start plugging one hub into another, you need to understand how USB C daisy chaining actually works.
The short answer is that yes, daisy chaining USB C hubs is possible when the hubs support the right standards and your computer has the bandwidth to handle it.
In this post, we’ll break down when you can daisy chain USB C hubs, why it sometimes fails, and what you should do instead to expand your ports.
Let’s get right into it.
Why You CAN Daisy Chain USB C Hubs in Certain Cases
The ability to daisy chain USB C hubs depends entirely on the protocol your devices use, not just the physical cable.
Thunderbolt 3 and Thunderbolt 4 hubs are designed to support daisy chaining, which means you can connect one hub to another in a chain.
USB4 hubs also follow this same rule, so if you’re working with these modern standards, daisy chaining USB C hubs can work smoothly.
1. Thunderbolt 3 and Thunderbolt 4 Hubs Support Daisy Chaining
When you daisy chain USB C hubs that are Thunderbolt-certified, each hub passes the signal through to the next device.
Thunderbolt 3 supports up to six devices in a chain, and Thunderbolt 4 offers similar flexibility with built-in security features.
So, if you have two Thunderbolt hubs, you can connect the first hub to your laptop, then plug the second hub into the first one.
This daisy chain USB C hubs setup works because Thunderbolt uses a point-to-point connection with enough bandwidth for multiple devices.
2. USB4 Hubs Follow the Same Daisy Chain Rules
USB4 is the newer universal standard that also supports daisy chaining USB C hubs, just like Thunderbolt.
The key is that USB4 hubs must have two upstream and downstream ports explicitly labeled for chaining.
You’ll see these marked with a daisy chain icon, and using those specific ports is critical.
When you daisy chain USB C hubs with USB4, you maintain speeds up to 40Gbps across the entire chain.
3. The Ports Must Support DisplayPort Alt Mode or Power Delivery Passthrough
For video signals, daisy chaining USB C hubs requires DisplayPort Alt Mode over Thunderbolt.
This allows you to connect monitors to different hubs in the chain without losing video quality.
Similarly, power delivery passthrough means each hub can still charge your laptop even when it’s not directly connected.
Without these features, daisy chaining USB C hubs will likely fail or cause drops in performance.
Why Daisy Chaining USB C Hubs Often Fails With Standard USB 3.0 or 3.1 Hubs
Here’s the catch: if you’re using regular USB 3.0 or USB 3.1 hubs, you cannot daisy chain USB C hubs the same way.
Most standard hubs are not designed to act as a passthrough device for another hub.
They only have one upstream port meant for the computer, and the downstream ports are for peripherals, not additional hubs.
1. Bandwidth Bottlenecks and Data Conflicts
When you attempt to daisy chain USB C hubs with standard hubs, you’re splitting the same bandwidth across multiple hubs.
Each hub adds its own overhead, and the data transfer speed drops significantly.
You might run into random disconnects, devices not being recognized, or extremely slow file transfers.
In most cases, the operating system will just give up and only recognize the first hub in the chain.
2. Power Limitations Cause Devices to Turn Off
Another big issue is power delivery.
Standard USB C hubs rely on their own power adapter, but when you daisy chain USB C hubs, the power gets shared.
The first hub might try to power the second hub, but most hubs aren’t built to provide that kind of wattage.
As a result, devices like external hard drives or monitors will flicker, fail to power up, or shut down randomly.
3. No Standardized Daisy Chain Protocol
The USB 3.x specification does not include a standard daisy chain protocol.
So even if you physically connect two hubs, the data simply doesn’t know how to flow through properly.
That’s why you’ll often see a message that says “USB device not recognized” when you try to daisy chain USB C hubs without Thunderbolt or USB4.
What to Do Instead of Daisy Chaining USB C Hubs
If daisy chaining USB C hubs isn’t working for you, don’t worry, there are better solutions that are more reliable and faster.
1. Use a Single High-Port Hub
Instead of trying to daisy chain USB C hubs, just buy one hub with more ports.
For example, a 16-port hub gives you plenty of USB-A, USB-C, HDMI, and Ethernet connections all in one device.
This avoids all the compatibility headaches and power issues that come with chaining.
2. Use a Thunderbolt Dock With Multiple Outputs
Thunderbolt docks are specifically designed to handle multiple devices, and they often have two or three downstream Thunderbolt ports.
You can connect one dock to your computer and then connect monitors or storage directly to that dock.
This is essentially daisy chaining USB C hubs, but using a proper dock that’s engineered for it.
3. Connect Hubs in a Star Topology Instead
A star topology means connecting each hub directly to your computer’s ports, not to each other.
If your laptop has two USB C ports, connect one hub to each port.
If you need more, use a powered USB C expansion card or a desktop USB hub with its own power supply.
This avoids the daisy chain USB C hubs limitations entirely and keeps every device running at full speed.
So, Can You Daisy Chain USB C Hubs?
You can daisy chain USB C hubs, but only if the hubs support Thunderbolt 3, Thunderbolt 4, or USB4.
If you’re using standard USB 3.0 or 3.1 hubs, daisy chaining will not work reliably and will likely cause disconnections and power failures.
The best approach is to check your hub’s specifications for daisy chain support and use the correct downstream ports.
And when in doubt, use a single high-port hub or a Thunderbolt dock to keep your setup simple and fast.
So yes, you can daisy chain USB C hubs with the right hardware, and now you know exactly how to do it without pulling your hair out.
