Frequently Asked Questions - HB20A4AME StarTech.com

Is the HB20A4AME USB hub compatible with USB 2.0 devices?

Yes, it is backward compatible with USB 2.0 and USB 1.1 devices, but at reduced speeds.

Does this hub require an external power adapter?

It is bus-powered when connected to a USB port, but for high-power devices (e.g., external hard drives), an optional 5V DC power adapter (not included) may be required.

Can I daisy-chain multiple HB20A4AME hubs?

Daisy-chaining is possible, but not recommended as it may cause signal degradation and power issues. For best performance, connect each hub directly to a USB port.

What is the maximum data transfer speed?

The hub supports USB 3.0 speeds up to 5 Gbps when used with USB 3.0 devices and ports.

Does the hub support charging of smartphones or tablets?

Are there any driver requirements?

No drivers are needed for Windows, macOS, or Linux. The hub is plug-and-play.

What do the LED indicators mean?

A green LED indicates the hub is powered. Blue LEDs (or per-port) show activity when data is transferred.

What is the warranty period?

StarTech.com offers a 3-year warranty from the date of purchase.
