Rugged, Industrial Grade, 4-Port SuperSpeed USB 3.1 Hub with High-Retention USB Connectors and Extended Temperature Operation

The USB3-104-HUB is a high performance, industrial grade, mountable solution for USB expansion. It is a high-speed USB 3.1 device, USB 2.0 and 1.1 compatible. Each of the four downstream ports are capable of SuperSpeed (5Gbps), Hi-Speed (480Mbps), Full-Speed (12Mbps), and Low-Speed (1.5Mbps) data transfers.

This product utilizes a high-performance, low-power USB 3.1 hub controller. It is USB-IF certified, Windows Hardware Quality Lab (WHQL) compliant, and its extended operating temperature is rated for industrial and military grade applications.

The USB3-104-HUB was designed to withstand a variety of environmental conditions such as shock, vibration, and temperature. This hub has latching / locking port connectors on both downstream and upstream ports to prevent accidental disconnects. The small, low profile, steel enclosure allows the device to be installed in numerous locations where multiple USB devices must share a single USB port. The rugged steel enclosure, positive retention connections, and extended temperature (-40°C to +85°C) operation makes the USB3-104-HUB stand out compared to commercially available USB 3.1 hubs.

Each card has light emitting diodes (LEDs) for status indications. A green LED near the upstream USB type B connector indicates power to the board. Each downstream port indicator lights Green, Blue, or Red, to indicate USB2/HighSpeed, USB3/SuperSpeed, or fault, respectively.

The USB3-104-HUB is fully protected from faulty peripherals connected to its downstream ports. Each port utilizes its own power distribution switch that provides overcurrent and short-circuit protection. If a fault occurs, the power distribution switch will disengage the respective port and illuminate its red fault LED. A fault occurring on one downstream port will not affect other devices attached to the USB-104-HUB’s other downstream ports. The disabled port can be re-enabled by clearing the fault and cycling power to the hub.

The USB3-104-HUB supports bus-powered and self-powered applications. Bus-powered mode is a limiting factor as downstream ports take power from the upstream port’s remaining available power. If downstream peripherals require more current, the USB3-104-HUB can be configured in self-powered mode. External +5V can be supplied to the card, which will provide 900mA (1200mA max.) to each downstream port. Power can be brought in via the DC locking jack / plug, or the 2-position screw terminal.

The USB3-104-HUB is designed to be used in rugged industrial environments but is small enough to fit nicely onto any desk or testing station. The board itself is PC/104 sized (3.550 x 3.775 inches, 90mm x 96mm) and ships inside a steel powder-coated enclosure with an anti-skid bottom. Mounting provisions available include a DIN rail and various panel mounting plates.


The OEM (board only) version is perfect for a variety of embedded applications. What makes the OEM option unique is that the PCB size and pre-drilled mounting holes match the PC/104 form factor (without the bus connections). This ensures easy installation using standard standoffs inside most enclosures or systems. The board can be added to any PC/104-based stack by connecting it to a USB port usually included on-board with embedded CPU form factors. The USB3-104-HUB OEM board can also be installed using standoffs inside other enclosures or systems.

High Retention USB Connectors

The ever-growing presence of USB in the industrial/military marketplace has driven the need for USB connections to be reliable, dependable, and unfailing. Gone are the days of loose USB connections. All type A and type B USB connections used on USB3-104-HUB product feature a high retention, locking design that complies with the class 1, Div II minimum withdrawal requirement. Over 11 pounds of force (50 Newtons), is required to separate the type A connectors. These connectors have a positive locking tab to quickly differentiate it from standard USB connectors. The Type B connection follows the USB3 Vision standard and features a screw lock USB cable to ensure secure connection to the USB3-104-HUB. Using the fastened USB connections on this hub increases reliability in your system and ensures against accidental disconnection.

Information about our Free Software packages:

ACCES is proud to provide a full suite of software support with every Data Acquisition product. We are committed to supporting the most popular operating systems and platforms for our customers. Currently we are actively supporting XP -> 10, both 32 & 64 bit, including “Server 2008,” “Embedded,” and “Compact” flavors for all plug-and-play products including PCI, PCI Express, USB, and more. Many products continue to ship with support for additional operating systems such as DOS, Windows 95, 98, Me, NT4, and 2000.


Among the software we deliver with our products are sample programs in a wide variety of programming languages. These samples are used to demonstrate the software interfaces to our products — and many can be used as-is in your production environments, or to test functionality of the devices out-of-the-box. We’re currently actively supporting sample programs in Microsoft Visual C#, Visual Basic, Delphi, and Visual C/C++, with many devices including samples in Borland C/C++ 3.1 for DOS. Additionally we provide National Instruments LabVIEW compatible DLLs and many demonstration VIs for our devices.


Drivers for various operating systems are also provided, including active support for Windows XP -> 10 — all in both 32-bit and 64-bit flavors, and including consumer, server, and embedded varieties — as well as the 2.6 and newer Linux kernels and recent OSX / macOS versions. Many products continue to ship with driver support for Windows 95, 98, Me, NT4, and Windows 2000, but support for these operating systems is considered deprecated.

Setup Programs and Utilites

Our Data Acquisition devices also include a graphical setup utility that walks you through the process of configuring any option jumpers or switches on the device, as well as explaining a little about the various connectors present.

Many devices also include utility programs – little tools to make your use of the device easier, such as EWriter, a program that allows you to read and write data in the user-accessible EEPROM locations on all our USB data acquisitition products; or WinRISC, a “Really Incredibly Simple Communications” terminal program that lets you get started instantly with serial devices.

“Register Level” Documentation

Besides all this software in all these languages and operating systems ACCES has a policy of open and transparent development: none of our lowest-level “register” interfaces are hidden from you — we document every register in every bus card, every command in every serial board, and every usb control transfer in every USB Data Acquisition board. These lowest-level interfaces allow you to develop for our products in ANY operating system or language, regardless of our actively supporting it or having a driver for it. We have customers actively developing in ADA, Android, Python, Java, MATLAB, Solaris, and more, just by referring to our complete low-level interface documentation! And we provide the full source code to all of our drivers, regardless of operating system, to give you an even bigger head start in your own development tasks.

No Fees or Royalties

All of this software is provided at no additional charge, and is licensed under any of a variety of flexible — and royalty free — options. Check out our software license explanation if you’d like more information.

Custom Software

ACCES also offers Custom Software Services for our products. Our prices are unbelievably low, often as inexpensive as free! If you need something tweaked to support your needs, or an entire enterprise application developed from scratch, it is definitely worth your time to inquire with us, first.
