Which Operating Systems Does the Flasher Hub-12 Control Software Support?
SEGGER's Flasher software package, which is used to set up the Flasher Hub-12, runs on Windows (x86-64 and Arm64), Linux (x86-64 and Arm64) and macOS (x86-64 and Apple Silicon). SEGGER provides a 64-bit Windows installer, DEB, RPM and TGZ packages for 64-bit Linux, DEB and TGZ packages for 64-bit Linux Arm, and Apple Silicon, Intel and Universal installers for macOS.
The hub's own web interface needs only a web browser, so day-to-day operation does not depend on the operating system of the PC.
-
When Should I Choose the Flasher Hub-12 Over the Flasher Hub-4?
Both hubs are used in the same way and share the same documentation. Each can control up to 24 Flasher Compact modules, and each channel can program a different device with a different firmware image. SEGGER describes a Flasher Hub-12 with multiple Flasher Compacts as the perfect solution for high-volume mass production. It brings 12 USB-C Flasher ports out directly instead of 4.
Flasher Hub-12 Flasher Hub-4 Maximum power supply 60 W 30 W Maximum power consumption 15 W 11.5 W Upstream host port USB Type-B USB-C 2.0 High Speed Enclosure Full chassis, with a chassis ground pin on the power connector Ground plate and plexiglass cover Weight (without cables) 660 g 135 g Both run from 8-30 VDC with reverse polarity protection, and both have Ethernet, RS232 9-pin and USB Type-A (downstream) host interfaces.
-
How Do I Set Up a Flasher Hub-12 for the First Time?
SEGGER describes the Flasher Hub as set up and ready to use in less than 10 minutes:
1Connect a supply of 8-30 VDC to the power connector. The Hub-12 connector has three contacts: (+), (-) and chassis ground.2Connect the LAN port. An Ethernet cable is optional according to SEGGER.3Connect each Flasher Compact to the hub with a USB-C cable.4Install the latest Flasher software package on a Windows, Linux or macOS PC.5Update the Flasher Hub firmware to the latest version.6Open the web interface at http://flasherhub-<serial number>/, using the serial number of your unit.If Flasher Compact modules sit behind USB hubs, the Flasher Hub must be configured for Flex Mode and the USB hubs must be powered externally.
-
What Can the Flasher Hub-12 Web Interface and FTP Server Show or Log?
The built-in web server (emWeb) is used for manual operation and monitoring. It shows:
- firmware and hardware versions
- power consumption
- IP configuration and network load
- the current operation and status
- the programming interface in use
The status information can help with troubleshooting, for example alongside a cyclic redundancy check (CRC) for code verification. It also lets you set options such as the subnet mask and gateway, and manages the firmware images and setup files for all connected modules.
The built-in FTP server (emFTP) is used to upload firmware and configuration files from a central production server and to download logs. Each log entry records the result (success or failure), the duration and the serial number if one was programmed. Failed cycles include troubleshooting detail.
-
Which Target Devices Can the Flasher Hub-12 Programme?
The hub controls the channels, but the supported CPU cores and target interfaces depend on the connected Flasher Compact modules rather than on the hub itself. SEGGER lists tens of thousands of devices in hundreds of device families, and the flash loaders for them are included in the Flasher software package.
A device that is not listed can be added with the Flasher SDK, which SEGGER sells separately. FPGAs and CPLDs are programmed with the Flasher BitStreamer, and the Flasher SDK is not required for that.
-
What Is the SEGGER USB Hub (5.01.10) and How Does It Differ From Standard Consumer USB Hubs?
The SEGGER USB Hub (listed by SEGGER as the USB Hub-7) is an industrial-grade, seven-port USB 2.0 Full-Speed hub for Flasher programming stations. It has one USB Type-B upstream port and seven USB Type-A downstream ports. SEGGER lists these features:
- Basic isolation on the upstream port, rated 3 kV DC for 1 second
- An overload limit on each downstream port
- High retention connectors on the upstream and downstream ports
- Testing to EN 61326-1, EN 55011 and EN 55024/55035
- Status LEDs
It is intended for gang programming with SEGGER Flasher Compact units and can connect up to 24 of them through a Flasher Hub-4 or Flasher Hub-12.
-
What Does the Electrical Isolation on the SEGGER USB Hub Protect?
The upstream port has basic isolation rated at 3 kV DC for 1 second, which SEGGER states protects the host system from electrical disturbances.
Safety note. The isolation is basic isolation only. SEGGER states that the hub is not for use with hazardous voltages without further protection measures. Where hazardous voltage is involved, a second protection measure (double or reinforced insulation) is mandatory, and the right method depends on the application. Check your local safety directives. -
What Power Supply Does the SEGGER USB Hub Need?
The SEGGER USB Hub runs from 8-30 VDC with reverse polarity protection and has a maximum power of 30 W, depending on the current drawn by the connected downstream devices. For maximum load, SEGGER specifies an input of 12 VDC or more.
Power connects through a screwable plug (Würth 691317510002, WR-TBL 3175) that accepts solid or stranded wire with a cross-section of 0.2-3.3 mm².
-
Can the SEGGER USB Hub Be Used with Non-SEGGER Devices?
Yes. It is designed for Flasher Compact gang programming, but SEGGER states it can also be used with other SEGGER products such as J-Link, and with other production programmers, including non-SEGGER products.
Using it with the Flasher Compact is optional. SEGGER recommends it because it is production grade, robust and tested, and notes that many hubs on the market are not fully standard compliant, are less reliable and lack electrical isolation.
-
What Are the Environmental and Physical Specifications of the SEGGER USB Hub?
- Operating temperature: +5 °C to +60 °C
- Storage temperature: -20 °C to +65 °C
- Relative humidity: below 90% rH, non-condensing

-
How Does the SEGGER USB Hub Extend a Flasher Hub-12 Beyond 12 Channels?
The Flasher Hub-12 has 12 USB-C Flasher ports. To go beyond 12 channels, put the hub into Flex Mode and connect Flasher Compact modules through powered USB hubs. With a Flasher Hub-4 or Flasher Hub-12, SEGGER states the SEGGER USB Hub can connect up to 24 Flasher Compacts, and each one can be assigned to any available channel.
-
What Is a High Retention Connector on the SEGGER USB Hub?
The hub has a high retention USB Type-B upstream port and high retention USB Type-A downstream ports. SEGGER describes the retention as there to keep cables secure in busy production environments.
-
Which Industrial Standards Is the SEGGER USB Hub Tested To?
The hub is tested to EN 61326-1, EN 55011 and EN 55024/55035. SEGGER describes these as covering electrical equipment for measurement, control and laboratory use. The CE declaration and other regulatory documents are available from SEGGER.
The hub is designed for production environments and industrial standards, which is relevant if your station has to meet EMC requirements for the equipment it sits beside.
-
Why Use an Industrial USB Hub for Gang Programming with the Flasher Hub-12?
Flex Mode needs powered USB hubs, and SEGGER states that USB hubs connected to the Flasher Hub must be powered externally. An industrial hub is built for this job:
- SEGGER notes that many hubs on the market are not fully standard compliant, are less reliable and lack electrical isolation.
- The SEGGER USB Hub has basic isolation on the upstream port, an overload limit on each downstream port and high retention connectors.
- It runs from the same 8-30 VDC range as the Flasher Hub-12.
- SEGGER only provides technical support for setups that use SEGGER USB hubs.
-
How Does the SEGGER USB Hub Fit Into Automated Test Equipment and Production Lines?
SEGGER designed the hub for production environments, and describes the Flasher Hub-12 as suited to panels with up to 24 devices, maximum speed, in-circuit test (ICT) where space is not critical, and space-distributed programming stations.
Once each channel has been set up on a PC, the Flasher Hub-12 can be controlled without one. It has a built-in ASCII command interface over TELNET and RS232, a web interface for manual operation and monitoring, and an FTP server for uploading firmware and configuration files and downloading logs. The SEGGER USB Hub supplies the extra downstream ports for the Flasher Compacts.
-
How Do I Connect Flasher Compact Units to the Flasher Hub-12?
In Direct Mode, each Flasher Compact connects to one of the 12 front-panel USB-C 2.0 High Speed ports. Each Flasher Compact needs a USB cable to the hub. Current Flasher Compacts use USB-C, while SEGGER's older setup tables list USB-C to USB-micro cables. In Flex Mode, up to 24 Compacts connect through powered USB hubs, such as the SEGGER USB Hub.
Each Flasher Compact acts as a separate programming channel. Over the hub it draws about 130 mA at 5 V, or about 230 mA if it also supplies a 100 mA target supply. The Compact housing measures 70 mm x 45 mm x 18 mm.
-
Which Flasher Hub-12 Interface Should I Use for Which Task?
Interface Specification Ethernet 10/100/1000 Mbit USB Type-B (upstream) USB 2.0 High-Speed USB Type-A (downstream) Listed by SEGGER as a host interface RS232 9-pin Serial, with the ASCII command interface Flasher ports 12 x USB-C 2.0 High Speed For automation, use the ASCII command interface over TELNET or RS232. The web interface (emWeb) is for manual operation and monitoring, and the FTP server (emFTP) handles firmware and configuration uploads and log downloads.
-
Can Each Programming Channel Be Configured Independently Through the Flasher Hub-12?
Yes. Each channel can run its own firmware image and settings, so different variants can be programmed at the same time, or every channel can run the same job for gang programming. Unique data can be programmed per device, including serial numbers, Ethernet MAC addresses, digital signatures and licence keys.
