This article covers StarTech.com 4ポートUSB 3.0ハブ.

Overview

The StarTech.com HB30AM4AB is a compact 4-port USB 3.0 hub that expands a single USB-A port on your laptop or desktop into four SuperSpeed 5Gbps ports. It supports USB 3.2 Gen 1 (formerly USB 3.0) and is backward compatible with USB 2.0 devices. Bus-powered design eliminates the need for an external power adapter, and the integrated 28cm cable wraps around the hub for easy storage and travel. Ideal for office and home-office environments where multiple peripherals need to be connected simultaneously. Weighing just a few dozen grams, this hub is purpose-built for mobile users with limited USB-A ports on ultrabooks, 2-in-1s, and Chromebooks. Its plug-and-play nature works across Windows, macOS, Linux, and Chrome OS without driver installation.

Connectivity & Compatibility

The hub provides four USB-A 3.2 Gen 1 (5Gbps) downstream ports. All ports share a combined power budget of 4.5W (5V/900mA) drawn from the host device's USB port – sufficient for most low-power peripherals like keyboards, mice, flash drives, and webcams. High-power devices (e.g., external SSDs requiring more than 900mA) may need a separate powered hub. It is fully compatible with USB 2.0/3.0 devices and operates on Windows, macOS, Linux, and Chrome OS. No additional drivers are required. The hub connects via a permanently attached 28cm USB-A cable.
