4-port USB 3.0 data hub
UGREEN 4-Port USB 3.0 Hub with 1m Cable (20291)
A compact USB-A host hub that expands one computer port into four USB-A 3.0 downstream ports for storage and everyday peripherals. Bandwidth and available bus power are shared.
Product introduction
Overview
A compact USB-A host hub that expands one computer port into four USB-A 3.0 downstream ports for storage and everyday peripherals. Bandwidth and available bus power are shared.
One upstream computer link shared by four downstream devices. Matching the connector shape alone is not enough: the host port, peripheral role, data generation, power requirement and installed driver must also be compatible.
This guide separates the headline interface ceiling from practical results and states what the exact SKU should not be used for, helping customers choose correctly before opening or routing the cable.
Quick reference
Key features
Exact length
1m attached host cable
Data capability
Up to 5Gbps USB 3.0 signalling shared across active devices; backward-compatible with USB 2.0/1.1

Connections and roles
How it fits into your setup
Host or source
Attached 1m USB-A 3.0 male host cable
Peripheral or downstream side
Four USB-A 3.0 female downstream peripheral ports
Connection role
One upstream computer link shared by four downstream devices
Power expectation
Bus-powered for ordinary use; exact official material shows an auxiliary 5V/2A input for stability with higher-demand devices
Real-world performance
Four ports share one 5Gbps upstream link and one power budget
The four sockets do not each receive an independent 5Gbps channel. Simultaneous transfers share the host connection and may slow one another.
A standard USB 3.0 laptop port can provide a limited bus-power budget. The auxiliary 5V/2A input can support hub stability but does not turn the ports into a charging station.
The LED shows connection/power status. Final behaviour depends on host controller, operating system, hub power and each peripheral.

Durability claims describe controlled product testing, not immunity from crushing, repeated sharp bends, liquid, corrosion or worn sockets. Grip the connector housing rather than pulling the cable.
Where it is useful
Use scenarios
Desktop peripheral cluster
Keep keyboard, mouse, printer and flash drive within reach from one computer port.
Storage access
Connect one supported external drive or card reader while respecting the shared power budget.
Console accessories
Use with compatible console USB peripherals where the console supports standard USB hubs.
Reach awkward ports
Bring rear desktop USB connections forward using the 1m attached lead.

Pre-purchase checklist
Check before buying
Connector shape
Attached 1m USB-A 3.0 male host cable; Four USB-A 3.0 female downstream peripheral ports.
Port roles
One upstream computer link shared by four downstream devices
Required performance
Up to 5Gbps USB 3.0 signalling shared across active devices; backward-compatible with USB 2.0/1.1
Power and video
Bus-powered for ordinary use; exact official material shows an auxiliary 5V/2A input for stability with higher-demand devices. No HDMI, DisplayPort or USB graphics function
What this product does
- Expands one USB-A host port into four USB-A data ports
- Supports shared USB 3.0 transfer up to 5Gbps
- Provides an LED status indication
- Accepts auxiliary 5V/2A power for hub stability where needed
What this product does not do
- Not a four-port fast charger
- Not a USB-C hub and does not fit a USB-C-only host without a suitable data adapter
- Not an Ethernet, HDMI, SD-card or audio dock
- Not guaranteed with every 2.4GHz wireless receiver, MIDI device or high-power peripheral
Installation workflow
Setup and usability guidance
- Connect the attached USB-A cable directly to the computer
- Connect low-power peripherals first and confirm each appears
- For demanding storage, use the auxiliary power arrangement specified in the manual
- Avoid crowding large plugs that place sideways force on adjacent sockets
- Eject storage safely before disconnecting the hub
Operating-system, driver and software guidance
The cable or hub normally has no standalone application. The connected device can still require its manufacturer driver, firmware, print queue, audio/MIDI setting, storage permission or USB mode. A physical connection cannot add a missing operating-system feature.
When troubleshooting, test one variable at a time: a direct host port, a known-good peripheral, the original device cable, an updated driver and a simple workload. This distinguishes cable, power, port and software faults.
Good practice
What to do
Verify first
Check SKU, connector, length, role, data generation and power expectation before ordering.
Use a direct path
Remove unnecessary adapters and hubs while installing or diagnosing the connection.
Support the plugs
Leave a gentle service loop and prevent cable weight from pulling on small sockets.
Test before routing
Complete repeated real tasks before hiding the cable behind furniture or inside management channels.
What not to do
Do not force a near-match
Stop when plug shape or insertion resistance is wrong. Similar USB connectors are not interchangeable.
Do not exceed the stated role
No HDMI, DisplayPort or USB graphics function. Bus-powered for ordinary use; exact official material shows an auxiliary 5V/2A input for stability with higher-demand devices.
Do not stack unknown links
Unsupported extensions and adapters reduce signal and power margin.
Do not ignore heat or damage
Unplug equipment that is wet, frayed, loose, crushed or unusually hot.
Read before use
Warnings and limitations
- Do not expect the hub to charge an iPad, tablet or several phones
- 2.4GHz wireless receivers and some MIDI/USB 3.0 devices can experience interference or compatibility limits
- The auxiliary input supports the hub; it does not increase the 5Gbps data ceiling
- Do not exceed the power-source rating or use an unknown damaged adapter
- For unstable hard drives, test direct to the computer and use the drive’s own power where provided
Performance reminder: advertised USB rates are theoretical ceilings. Real results depend on the slowest compatible component and on shared bandwidth, software, workload and power conditions.
Diagnose methodically
Troubleshooting by symptom
Not detected
Confirm the exact connector and port role; test direct without a hub and restart the peripheral.
Connects then drops
Inspect for loose ports or cable strain, simplify the link and reduce bus-power demand.
Transfer is slow
Verify every endpoint supports the advertised USB generation and test with one large file.
Printing or scanning fails
Install the manufacturer driver, select the correct device and clear stalled print/scan jobs.
Works on one computer only
Compare drivers, USB power settings, security permissions and port capability.
Charging is weak or absent
Review the stated power role; this product may be data-focused and cannot add a charging protocol.
Video is absent
Use a dedicated video-capable solution unless the exact product explicitly supports USB-C display mode.
