In industrial environments, data centers, or laboratories, USB devices such as dongles, data loggers, printers, or measuring systems are often difficult to access. The USB Device Server Megabit – 2x USB 2.0 from Wiesemann & Theis solves this issue by seamlessly integrating USB devices into TCP/IP networks. This allows USB devices to be accessed over the network, regardless of location or system – as if they were directly connected to the local computer.

With two USB 2.0 ports, Power-over-Ethernet (PoE), optional galvanic isolation, and support for all USB operating modes, this compact device provides a universal solution for Industry 4.0, automation systems, and virtual IT environments such as VMware or Hyper-V.

Full USB functionality over TCP/IP

The USB Device Server provides up to two USB 2.0 interfaces accessible through the network. Together with Wiesemann & Theis’ USB redirection software, connected USB devices appear directly in the PC’s plug-and-play system. Multiple USB modes are fully supported:

• Control: for device control interfaces such as dongles or configuration adapters
• Bulk: for mass data transfers, e.g., printers or storage media
• Interrupt: for input devices like barcode scanners or RFID readers
• Isochronous: for time-sensitive devices like audio or video hardware

The device functions identically to a locally connected USB peripheral – with no restrictions regarding data types or transfer methods.

Share and extend USB over the network

USB devices can be accessed by multiple computers via Ethernet. Software dongles particularly benefit from this centralized setup because they can be securely installed in a server room and shared across the network. This ensures that expensive or security-sensitive USB devices are used efficiently and safely.

The device also acts as a USB extender, increasing range from a few meters to hundreds of meters across a LAN while maintaining stable, interruption-free communication. After temporary network disconnections, devices are automatically reconnected through the auto-reconnect function.

Use in virtual environments

Many virtualization platforms, such as VMware, Hyper-V, or VirtualBox, do not support direct mapping of physical USB ports to virtual machines. The USB Device Server Megabit solves this issue using software-based USB redirection directly into the virtual machine’s operating system. This allows real USB devices to operate in environments without physical USB interfaces.

The integration is driver-based, ensuring deep system-level access and consistent device recognition across host and guest operating systems.

Industrial robustness and galvanic isolation

The hardware of the USB Device Server Megabit – 2x USB 2.0 is designed for maximum reliability. Optional galvanic isolation protects connected USB devices and the network from voltage spikes and ground loops. Each of the two USB ports supports up to 500 mA, enabling safe operation even for power-intensive peripherals.

The device’s industrial-grade construction allows reliable operation in demanding environments, from production lines and test laboratories to measurement stations and control centers.

Power-over-Ethernet (PoE) and alternate power options

The USB Device Server can be powered either via Power-over-Ethernet (PoE) or through an external DC power input (24–48 V). This flexibility reduces cabling complexity and enables operation even in locations without a dedicated power line. The Ethernet port (100BaseT) supports autosensing and auto-MDIX for seamless network integration.

Easy setup and intuitive management

Setup is simplified by the WuTility software: once connected to the network, the device is automatically detected and can be configured with just a few clicks. Through the integrated web interface, administrators can manage user rights, port assignments, and IP settings. DHCP support allows easy integration into existing networks, and remote management is available via HTTPS or Telnet.

Comparison with USB-over-IP alternatives

Unlike simple USB extenders that only operate point-to-point, the Wiesemann & Theis USB Device Server offers full network integration with multiple simultaneous users and complete USB functionality. No manufacturer compatibility lists or special device drivers are required since all USB modes are supported.

For professional and industrial applications, this provides a more reliable, secure, and durable solution than traditional USB extender setups.

Typical application areas

• IT and server environments: centralized management and shared access to USB dongles, printers, or storage devices
• Automation: connecting control systems or card readers via network
• Measurement technology: collecting sensor data via USB measurement adapters from remote areas
• Research and laboratory environments: accessing specialized devices remotely without physical interaction
• Distributed office environments: network-based access to scanners or signature pads

Standards compliance and reliability

The USB Device Server meets industrial and EMC standards (EN 61000-6-2 and EN 55032:2015 + A1 Class B). Its robust electronics and surge protection make it suitable for continuous operation in demanding conditions. Wiesemann & Theis provides a five-year warranty for the device.

USB wherever you need it

The Wiesemann & Theis USB Device Server Megabit – 2x USB 2.0 eliminates the limitations of traditional USB cable length. Devices connected to the network can be accessed securely from any workstation at any time – whether in an office, manufacturing plant, or laboratory.

With USB redirection, PoE support, and optional galvanic isolation, it offers flexibility, stability, and long-term reliability for USB-based peripherals in modern industrial and IT applications.
