This article covers StarTech.com 4ポートUSB 2.0ハブ 本体一体型ケーブル コンパクトミニUSBハブ バスパワー対応 ST4200MINI2.

Overview

The StarTech.com ST4200MINI2 is a compact USB 2.0 hub that expands a single USB port into four. Its tiny footprint makes it an ideal travel companion for laptop users who need extra ports for a mouse, keyboard, or USB flash drive. The hub is bus-powered, so no external power adapter is needed — just plug it into any free USB port and you're ready to go. Maximum throughput is 480Mbps, which is sufficient for most peripherals. The attached USB cable (about 6 inches / 15 cm) is permanently fixed to the hub, so you never have to worry about losing it. All four ports are arranged on one side of the device, making it easy to plug and unplug multiple gadgets without awkward fumbling. The ST4200MINI2 is truly plug-and-play: Windows, macOS, Chrome OS, and Linux all recognize it immediately with no driver installation required.

Connectivity & Compatibility

Interface: USB 2.0 (4 downstream ports) Compatible devices: Mice, keyboards, USB flash drives, bus-powered external HDDs, smartphones (data sync only) Supported OS: Windows / macOS / Chrome OS / Linux Power: Bus-powered (total current draw of connected devices should not exceed 500 mA for stable operation) * Cable: Attached, approximately 15 cm (6 inches) Important caveat: this hub operates only at USB 2.0 speeds (480 Mbps). Connecting a USB 3.0 or 3.1 device will degrade its performance to USB 2.0 levels. Also, because it is bus-powered, you should avoid connecting power-hungry devices like portable hard drives with mechanical platters — they may not spin up reliably.

Product Info

The ST4200MINI2 is positioned as an entry-level USB hub, first released around 2016. It remains a solid choice for basic port expansion. Typical retail price is about ¥2,000 (around $14 USD). StarTech.com backs it with a 2-year warranty and free lifetime technical support. The package includes only the hub itself; no extra cables or power adapters are needed. It is widely available on Japan and other e-commerce platforms. In the market, it serves the niche of users who need a no-fuss, affordable, and trustworthy USB 2.0 hub. If you require high-speed data transfer or USB-C connectivity, this is not the right product. But for everyday peripherals, it is perfectly adequate.

Best Use Cases

Laptop users on the go: The compact size and attached cable make it easy to carry in a laptop bag. Perfect for adding a mouse and USB key to a notebook with limited ports. Minimalist desk setups: If your desktop PC has rear-facing USB ports, this hub brings four ports to your desk without a tangle of cables. Great for keyboards, mice, and card readers. * Budget-conscious buyers: At around ¥2,000, it offers reliable expansion without breaking the bank. Ideal for users who do not need USB 3.0 speeds (e.g., for keyboards and mice). It is not recommended for users who need to connect high-speed external SSDs, charge smartphones rapidly, or run multiple power-hungry devices simultaneously.

Things to Consider

The hub supports only USB 2.0 (480 Mbps). If you need USB 3.0/3.1 speeds, look elsewhere. Bus-powered design means total power is limited to 500 mA. Daisy-chaining multiple devices may cause intermittent disconnections. For power-heavy setups, consider a self-powered hub. With only four ports, heavy multi-device users may outgrow it quickly. The attached cable is fixed — if it breaks, the entire hub must be replaced (warranty applies). ## FAQ
Q: What happens if I plug a USB 3.0 device into this hub? A: The device will work but only at USB 2.0 speeds (max 480 Mbps). This is fine for most keyboards, mice, and printers linkedin—just not for large file transfers. Q: Can I charge my smartphone using this hub? A: It can supply up to 500 mA, which is the standard USB 2.0 charging rate. For fast charging (e.g., Qualcomm Quick Charge or USB PD), you need a dedicated charger. Data sync works normally. Q: Does it require any driver installation? A: No. It is plug-and-play on all major operating systems. Just plug it into a USB port, and the hub appears immediately as four additional ports.
