UGREEN CM475 USB 3.0 to 3×USB Hub + Gigabit Ethernet Converter

Expand the connectivity of your laptop or desktop with the UGREEN CM475 USB 3.0 Hub with Gigabit Ethernet Converter. It transforms a single USB 3.0 connection into three high-speed USB-A ports while adding a Gigabit RJ45 Ethernet port, giving you convenient access to peripherals and fast, stable wired networking from one compact adapter.

With USB 3.0 data transfer speeds of up to 5Gbps and Gigabit Ethernet supporting 10/100/1000Mbps, the CM475 is ideal for connecting external drives, flash disks, keyboards, mice and other USB accessories while providing a reliable wired internet connection.

Key Features

Expand One USB Port into Three

The CM475 adds three USB 3.0 Type-A ports, allowing you to connect multiple peripherals to a computer with limited USB connectivity.

Connect devices such as:

• USB flash drives
  
• External hard drives and SSDs
  
• Keyboard and mouse
  
• Printers
  
• Card readers
  
• USB adapters and other peripherals
  

Up to 5Gbps USB 3.0 Data Transfer

The three USB ports support USB 3.0 with theoretical transfer speeds of up to 5Gbps, making the CM475 suitable for transferring files and accessing external storage considerably faster than USB 2.0. It is also backward-compatible with USB 2.0 devices.

Gigabit Ethernet for Stable Wired Internet

Need a wired network connection? The built-in RJ45 Gigabit Ethernet port supports 10/100/1000Mbps auto-negotiation, allowing compatible computers to connect to a wired network at up to 1Gbps.

This is particularly useful for laptops without a built-in Ethernet port, or when you need a more stable connection for large downloads, video streaming, online meetings, file transfers or other network-intensive activities.

Practical Solution for Modern Laptops

The CM475 is useful when your computer has limited connectivity but you still need access to traditional USB-A peripherals and wired networking.

Instead of carrying separate USB and Ethernet adapters, the CM475 combines both functions into one compact device.

Compact & Portable Design

Its compact construction makes it easy to keep in your laptop bag, backpack or desk drawer. The aluminum-alloy construction used in listed CM475 variants also helps with durability and heat dissipation.

Plug & Play Convenience

The Ethernet adapter is designed for straightforward installation, with driver-free operation supported on Windows 8/8.1/10 and macOS according to the CM475 documentation. Linux is also listed among supported operating systems.

One Adapter for USB Expansion & Wired Networking

The UGREEN CM475 is particularly useful for laptops and PCs that need more USB connectivity without sacrificing the option of a wired network connection.

For example, you can connect an external storage drive, keyboard and mouse through the three USB ports while using the RJ45 port for a wired internet connection.

It is a practical accessory for home offices, business users, students, IT technicians and anyone working with a laptop that has limited ports.

Important Compatibility Note

Make sure your computer has the appropriate USB 3.0 host port before purchasing. USB 3.0 can provide up to 5Gbps theoretical data transfer, but actual speeds depend on the connected device, computer, storage drive and other factors.

Similarly, the Gigabit Ethernet rating represents the maximum supported network link speed; actual internet speed depends on your network connection and networking equipment.
