Frequently Asked Questions - EU-HB4S Edimax

How do I install the Edimax EU-HB4S USB hub?

Plug the DC adapter into the hub and an electrical outlet. Connect the upstream port (Type B) to your computer using the included USB cable. Then connect your devices to the downstream ports. The LEDs will light up to indicate power and connection status.

Does the hub require a power adapter or can it be bus-powered?

The EU-HB4S supports both self-powered and bus-powered modes. It automatically selects the best mode. However, for power-hungry devices, it is recommended to use the included power adapter to ensure stable operation.

How many devices can I connect to this hub?

The hub has 4 downstream ports, but through daisy-chaining other hubs, it can support up to 127 USB devices in a tiered-star configuration as per USB 2.0 specifications.

What do the LED lights indicate?

Each port has an LED: a green light indicates power is on, and a red light indicates that port is operating at USB 2.0 high-speed (480 Mbps).

Is the hub compatible with USB 3.0 devices?

Yes, but only at USB 2.0 speeds (up to 480 Mbps). The hub is not USB 3.0 certified, so USB 3.0 devices will operate in backward-compatible USB 2.0 mode.

What is the maximum current per port?

Each downstream port can provide up to 500 mA, which is standard for USB 2.0. For devices requiring more power, use self-powered mode.

Does the hub have over-current protection?

Yes, it features automatic per-port over-current detection and recovery. If a device draws too much current, that port will be temporarily disabled to protect the hub and other devices.

Can I use the hub with Linux, macOS, or Windows?

Yes, the hub is operating system independent. It uses standard USB drivers, so it works with Windows, macOS, Linux, and other systems that support USB HID or mass storage devices.

What is the operating temperature range?

The hub operates from 0°C to 40°C and can be stored between -20°C and 60°C. Keep it away from extreme heat or moisture.

How do I clean the USB hub?

Disconnect the hub from power and computer. Wipe the exterior with a soft, dry cloth. Do not use liquids or sprays, as they may damage the electronics.
