This project is not affiliated with, endorsed by, or supported by StarTech.com.

StarTech's proprietary cusbi and cusba programs are not included.

Install

python3 -m pip install st-uhubm

Install with the optional web GUI:

python3 -m pip install "st-uhubm[gui]"

Download the StarTech Linux control program from the product's Drivers & Downloads page and place it on PATH:

• cusbi on x86 and x86-64
• cusba on ARM and AArch64

Command line

stuhubm health
stuhubm list
stuhubm status /dev/ttyUSB0

stuhubm off /dev/ttyUSB0 3
stuhubm on /dev/ttyUSB0 3

stuhubm off /dev/ttyUSB0 2,3,4
stuhubm on /dev/ttyUSB0 all

JSON output:

stuhubm --json status /dev/ttyUSB0

Custom control-program path:

stuhubm --binary /opt/startech/cusbi health

Web GUI

stuhubm-gui

Open http://127.0.0.1:8080.

Use another address or port:

stuhubm-gui --host 0.0.0.0 --port 9000

Python API

from st_uhubm import discover

hub = discover()[0]

hub.set_port(4, on=False)
hub.set_port(4, on=True)

for port in range(1, hub.n_ports + 1):
    for device in hub.identified_devices(port):
        print(port, device.product, device.serial)

Device identification

Device identification uses Linux sysfs and requires no additional Python package.

Currently recognized:

• SEGGER devices with USB vendor ID 1366
• Nordic PPK2 devices with USB ID 1915:c00a

The application accounts for the internal cascaded USB topology of supported seven-port hubs and associates identified devices with managed ports.

Permissions

The StarTech control program normally requires permission to access the hub's control device, such as /dev/ttyUSB0.

By default, st-uhubm runs the program through sudo. To run without sudo, grant the user access to the device.
