USB hub Lian Li PW-U2HB — 3x USB-A 2.0 ports

Lian Li PW-U2HB is a compact USB hub that provides three USB‑A 2.0 ports to expand a computer or compatible device's connectivity. The hub offers simple plug‑and‑play operation and is designed to attach to a desktop or laptop for additional legacy USB‑A connections. Its small footprint and straightforward functionality make it a practical accessory for connecting keyboards, mice, printers, flash drives and other low‑speed USB peripherals.

Advantages

The hub requires no additional drivers and works with standard USB host ports, offering reliable data transfer for peripheral devices that use the USB 2.0 protocol. Its compact enclosure and three-port layout allow convenient placement on a desk or near a workstation while keeping cables organized. The device is compatible with a wide range of operating systems and hardware that support USB‑A connections, providing a simple expansion option when native ports are limited.

Suitable for

• Connecting keyboards and mice to desktop or laptop computers
• Attaching printers or scanners that use USB‑A connections
• Accessing data from flash drives and external storage with USB 2.0 speeds
• Expanding port availability on older systems with limited USB‑A sockets
• Temporary workstation setups where compact, no‑driver hubs are needed

Key specifications

• Interface: Three USB‑A downstream ports, USB 2.0 (High Speed up to 480 Mbps)
• Power: Bus‑powered from host USB port (no external power adapter)
• Compatibility: Works with devices supporting USB 2.0/1.1/1.0 protocols
• Form factor: Compact, lightweight hub suitable for desktop or laptop placement
• Plug‑and‑play: No additional drivers required on standard operating systems

How to use

Connect the hub's upstream USB plug to an available USB port on your computer or compatible device. Once connected, the operating system should recognize the hub and make the three downstream USB‑A ports available for peripherals. Attach keyboards, mice, flash drives or other USB‑A devices to the hub; devices that require additional power or high data throughput may not perform at the same level as when connected directly to a powered or USB 3.x port.

Recommendations

For optimal results, use the hub with low‑to‑moderate power devices such as input peripherals and flash drives. Avoid connecting multiple high‑power or high‑bandwidth devices simultaneously, as the hub is bus‑powered and operates at USB 2.0 speeds. If you need to connect external hard drives or charge power‑hungry devices, consider a powered hub or a USB 3.x solution.
