Frequently Asked Questions - COM-079 Steren

Does the Steren COM-079 require driver installation?

On most operating systems (Windows, macOS, Linux), the COM-079 is plug-and-play and does not require additional drivers. An driver may be needed for very old systems like Windows 98.

Can I use this hub with USB 3.0 devices?

Yes, USB 3.0 devices are backward compatible with USB 2.0 ports, but they will operate at USB 2.0 speeds (up to 480 Mbps).

Does the hub provide enough power for external hard drives?

The hub is bus-powered and may not provide sufficient power for high-power devices like 2.5" external hard drives. Use a powered hub for such devices.

What is the maximum number of devices I can connect?

The hub has 4 USB ports. You can connect up to 4 devices simultaneously, but note that total power is limited.

Is the Steren COM-079 compatible with my tablet or smartphone?

If your tablet or smartphone supports USB OTG (On-The-Go), you can use the hub to connect USB peripherals like keyboards, mice, or flash drives. The hub itself is USB OTG compatible.

How do I know if the hub is working?

When connected to a powered-on computer, the hub's LED indicator should light up. If it does not, check the USB connection and try a different port.

Can I charge devices through this hub?

The hub is not designed for charging; it is for data transfer and low-power peripherals. Charging current is limited to 500 mA per port, which is insufficient for most phones and tablets.

What should I do if a connected device is not recognized?

First, try reconnecting the device or plugging it into a different port. Ensure the device driver is installed. If the problem persists, try connecting the hub to a different USB port on your computer.

Does the hub support USB 2.0 High-Speed?
