PAINLESS PRESENTATIONS
With Acroname’s auto-switching technology, when a user’s host device (Laptop) is plugged in to the USBHub3+ Up0 port, any USB peripherals connected to USBHub3+ will then automatically switch to that user’s host device.
COMPLETE CONTROL
The USBHub3+ is an intelligent USB hub with per-port control. Eight (8) down-stream programmable USB-A ports with individual on/off control that can measure individual port voltage, current and data speed. Perfect for device testing and software regression labs where device charge control is needed to mitigate battery-swell.
COLD SECURE BACKUPS
USBHub3+ gives you the power to create cold secure daily offline backups with just a small script. Preventing takedowns from ransomware.
INDUSTRIAL GRADE RELIABILITY
The USBHub3+ is built for the most demanding conditions when failure isn’t an option. With a rugged steel enclosure, ±15kV ESD protection, and DIN rail mountable. It is ready for the harshest of factory floors, device farms, laboratories, or CEO-laden conference rooms.
POWERFUL AND FULL OF POWER
While most USB hubs struggle to charge a phone, the USBHub3+ can supply up to 5A on all ports with a maximum total power of up to 70W. This hub will not even break a sweat with eight 4k cameras connected.
Features:
- Supports USB hosts and devices up to USB 5Gbps; backwards compatible with USB1, USB2
- Individually enable/disable any of 8 downstream ports
- Measure voltage and current on each downstream port
- Hi-Speed data, SuperSpeed data and power lines can be separately enabled for each downstream port
- Set programmable current limits for each downstream port (up to 4A)
- Dedicated Control Port for software control; independent of the selected upstream port
- Select between two (2) host connections
- All ports support USB link speeds up to 5Gbps
- Detect established link speed on each port: SuperSpeed (5Gbps) or Hi-Speed (480Mbps)
- Supply up to 5A per port; measure upto 4A
- Set enumeration delay for discovery of attached downstream devices
- Backward compatible with USB 2.0 and USB 1.x devices
- Boost USB 2.0 upstream and downstream signal levels
- DIN-rail mountable
- Alternate Euro-style terminal block power input connector
- Certified to +/-15kV ESD strikes (IEC61000-4-2 level 4)
- Overvoltage and reverse current protected Vbus outputs
- Monitor voltage and current on any/all ports
- Maintain selectable control of data, SS lines, power lines for any port
- Enable/Disable any downstream port

SOFTWARE CONTROL
The USBHub3+ is built on Acroname’s BrainStem system, which provides simple high-level APIs, a real-time embedded runtime engine and modular expandability.
Software control of the features of the USBHub3+ is done with the BrainStem API via a BrainStem link. BrainStem links are done over USB and can be established via upstream port 0 (Up0), upstream port 1 (Up1), or the Control Port. After one or more of these ports is connected to a host machine, a user can connect to it via software on the host. An example graphical user interface application is available at https://acroname.com/software. Functionality details unique to the USBHub3+ are in the online API documentation. For more information on getting started with software control of the USBHub3+, see the online reference documentation at https://acroname.com/reference/.
BrainStem Control Port
By integrating Acroname's BrainStem technology, the USBHub3+ can be controlled with a simple and powerful programming API in C++ and Python. Acroname also provides HubTool as an example application which can be used to quickly setup or control the hub. The BrainStem APIs and HubTool is available on all modern operating systems (macOS, Linux, and Windows 11 - Windows 7 (32bit and 64bit)). And of course, the BrainStem platform provides an embedded virtual machine API. This embedded RTOS allows for completely automatic control of all features of the USBHub3+ without needing a host PC.
The latest BrainStem development API is always available in the Download Center. The latest firwmare can be applied using the Updater utility. Check out the BrainStem Firmware Management reference entry or video for instructions on how to update your device.
HUBTOOL
HubToolis an example application utilizing the Qt GUI framework. Source code for HubTool is available in theDownload Center, which can serve as a quick start to writing your own GUI application to meet your needs. It also serves as a good entry tool for understanding the functionality of the USBHub3+, or just watching the battery charge curves of your various devices.
Let Acroname help you take charge of USB in ways you had not previously thought possible.
