UGREEN 30m USB 2.0 Active Extension Cable (10326)
Overview
This 30 m US121 cable extends one USB-A peripheral connection beyond the practical reach of an ordinary passive lead. A built-in active repeater restores the data signal along the run. The USB-A male end connects to the host; the USB-A female end accepts the peripheral plug or its USB-A cable. It supports USB 2.0 data up to 480Mbps and is intended for compatible low-power peripherals.

What it does well.
Key features
Active repeater. The US121 design is active repeater; that determines signal reach and whether extra electronics are present.
Up to 480Mbps. The listed ceiling applies only when every relevant host, cable segment, adapter and peripheral supports the negotiated USB mode.
30 m reach. Measure the routed path around furniture and leave gentle slack. Do not stretch the cable, pinch it under furniture or make tight bends at either connector.
Power behaviour. Bus-powered; no auxiliary-power input is shown or specified. No PD or fast-charge rating.
Use scenarios
Workspace reach. A printer or scanner placed farther from a desktop USB-A host
Peripheral placement. Keyboard, mouse, barcode reader or other modest-power USB 2.0 peripheral
AV or imaging. A webcam or security-camera data link only after checking power and software needs
Long-route planning. A controlled equipment run where the 30 m route is required
A device category is not a compatibility promise. Confirm its connector, USB mode, driver, power demand and manufacturer guidance for extensions before permanent routing.
Setup and usability guidance
- Test direct first: confirm the peripheral works when connected straight to the host.
- Identify the host end: connect the male plug to the host/source and the female socket to the peripheral side.
- Simplify: remove unnecessary hubs, adapters and other extensions during setup.
- Connect securely: insert straight, support the cable weight and avoid side-load on either port.
- Verify the real task: test sustained transfer, printing, recording, wake/reconnect or display/charging as applicable—not only initial detection.
- Route last: once stable, use broad bends, dry indoor placement and strain relief.
Compatible devices and systems
Windows, macOS, Linux and ChromeOS hosts can use standard USB class drivers. The cable itself needs no separate driver, but the connected printer, camera, scanner or specialist peripheral may require its own driver or application. USB 3.x Type-A ports are normally backward-compatible with USB 2.0 signalling, with the link limited to USB 2.0 speed.
Host requirement. A functioning USB-A male host/source port with support for the required USB mode.
Peripheral requirement. A compatible USB-A female connection, suitable device driver and a power demand the complete setup can meet.
Backward modes. Backward operation uses the slowest mutually supported USB mode. A faster-labelled host port cannot raise the capability of a slower cable or device.
No cable driver. The extension itself is plug-and-play. Specialist devices may still need vendor software, permissions, firmware or a particular host controller.
What this product does
- Extends one USB-A data path by 30 m.
- Regenerates the USB 2.0 signal with built-in active electronics.
- Passes ordinary USB bus power from the host for compatible low-power operation.
- Supports plug-and-play cable operation; peripheral software remains device-specific.
What this product does not do
- It does not exceed the USB 2.0 ceiling of 480Mbps.
- It does not carry HDMI, DisplayPort Alt Mode or other native display video.
- It does not support USB Power Delivery and is not sold as a charging extension.
- It does not provide an auxiliary-power socket or replace a powered USB hub.
- It does not convert USB-A to USB-C or change the peripheral protocol.
What to do
Match the full chain. Check both connector ends, host capability, peripheral requirements, any downstream lead and the application before installation.
Protect the ports. Support the cable and leave a service loop. Hold the plug housing when disconnecting; do not pull or twist the cable.
Plan peripheral power. There is no documented auxiliary-power input on this cable. The repeater and a compatible peripheral draw from the host USB port. If a device disconnects, fails to start, uses a motor/heater/high-output lighting, or normally needs more power than the host can supply, use the device’s own approved power arrangement or a suitable powered hub near the peripheral.
Keep evidence simple. If troubleshooting, change one variable at a time and test direct operation before adding the extension back.
What not to do
Do not join two hosts. Never connect two powered host ports; USB host-to-host wiring can cause damage.
Do not force connectors. USB-A and USB-C are different. Stop if a plug does not align, and never use a loose or damaged socket.
Do not build a cable chain. No supported chain count is published. Extra leads, adapters and hubs reduce signal and power margin.
Do not trust legacy name lists. The current page retains historical examples involving older VR, Kinect and PlayStation camera ecosystems. Those names are not treated as present-day compatibility certifications. The live media is family-style and does not print the length, so captions do not infer length from the photograph.
Warnings and limitations
Speed: Up to 480Mbps is an interface ceiling, not guaranteed application throughput.
Power: follow the power guidance above; device detection alone does not prove adequate power under load.
Video: No native video output. Connector shape alone does not establish display support.
Chaining: use one suitable length; no supported daisy-chain count is published.
Condition: keep dry, avoid heat, crushing and tight bends, and stop using damaged or unusually hot connections.

Questions buyers ask.
Is 10326 passive or active?
Active. An inline repeater regenerates USB 2.0 data over the long run. “Active” describes signal electronics; it does not mean a separate mains adapter is supplied or required for normal compatible use.
Which end goes where?
Plug the USB-A male end into the computer or other USB host. Connect the peripheral, or its USB-A plug, to the USB-A female end. It is not intended to join two host computers.
What is the highest data rate?
Up to 480Mbps under USB 2.0. Actual transfers depend on the host controller, peripheral, storage media, drivers, protocol overhead and the rest of the connection.
Does it have an auxiliary power port?
No auxiliary input is shown or specified for this US121 model. It uses power available from the host USB connection; that does not guarantee enough power for every peripheral.
Can I charge a phone through it?
Do not select it for charging. It has no USB Power Delivery or fast-charge rating, and long-cable voltage drop can further limit charging behaviour. Use a suitable charger and charging cable instead.
Can it carry a monitor signal?
No native HDMI, DisplayPort or USB-C Alt Mode video is provided. A specialist USB graphics device would still depend on its own documented USB 2.0 compatibility, software and bandwidth.
Will it work from a USB 3.0 computer port?
Usually for USB 2.0 devices because USB-A USB 3.x host ports commonly support USB 2.0 fallback. The extension itself remains USB 2.0 and cannot deliver 5Gbps.
Can I connect another extension to it?
A supported chaining count is not published. Use one correctly sized cable; chained leads increase signal, connector and voltage-drop risk and are not promised.
Will every webcam or security camera work?
No universal guarantee is possible. Confirm that the device uses USB 2.0, fits the power budget, supports the host operating system and tolerates an active extension. Test recording, wake and reconnect behaviour.
What about Oculus, HTC Vive, Kinect or PlayStation cameras?
Treat older product-page examples as historical, not as current certification. Revisions, firmware, timing and power requirements vary. Check the current device maker’s cable guidance before buying.
What should I check if it disconnects?
Connect the peripheral directly first, try another host port, remove hubs/adapters, update the device driver, inspect plugs, reduce other USB power load and test the full application—not only device detection.
