UGREEN USB-C to USB 3.0 Hub + Gigabit Ethernet-CM475

The UGREEN CM475 USB-C Hub with Gigabit Ethernet is a practical connectivity solution for modern laptops and other USB-C devices with limited ports. It combines a high-speed three-port USB hub and Gigabit Ethernet adapter into one compact device. Whether you need to connect external storage, a keyboard and mouse or access a reliable wired network, the CM475 provides the essential connections through a single USB-C port.

3 × USB 3.0 Ports

The CM475 provides three USB 3.0 Type-A ports, allowing several USB peripherals to be connected simultaneously. The ports support theoretical data transfer speeds of up to 5Gbps.

You can connect devices such as:

• External HDDs and SSDs
• USB flash drives
• Keyboards and mice
• USB receivers
• Card readers
• Printers
• Cameras and other USB peripherals

Gigabit Ethernet up to 1000Mbps

The integrated RJ45 port supports automatic negotiation at: 10Mbps / 100Mbps / 1000Mbps. This gives laptops without built-in Ethernet an easy way to connect directly to a wired network. Gigabit Ethernet is particularly useful for office networks, large file transfers, cloud applications, video conferencing and situations where Wi-Fi is weak or unstable.

One Adapter for USB and Network Expansion

The basic configuration is: USB-C Host → CM475 → 3 × USB-A + Gigabit RJ45. This makes the adapter useful for modern ultrabooks that have only a few USB-C ports.

USB 3.0 High Speed Data Transfer

With USB 3.0 offering theoretical transfer speeds of up to 5Gbps, the CM475 can handle significantly faster file transfers than USB 2.0 when used with compatible storage devices. It is also backward compatible with older USB peripherals, although their performance remains limited to their respective USB standard.

Stable Wired Networking

For business users, the Ethernet connection is one of the biggest advantages of the CM475. A typical office setup can be: Laptop → CM475 → Ethernet Cable → Network Switch/Router. At the same time, the remaining USB ports can accommodate a keyboard, mouse, external drive or other peripherals.

Plug and Play

The CM475 supports major operating systems, including Windows, macOS and Linux. UGREEN’s manual states that Ethernet is driver-free on Windows 8/8.1/10 and macOS, while older Windows 7 installations may require a driver.

Compact Design

The compact design makes the CM475 suitable for both permanent office installations and mobile users. It can easily be carried alongside a laptop, making it useful for business travellers, IT professionals, students and remote workers.
