Product Features
Technical Overview
This USB/Ethernet combo hub delivers USB 3.2 Gen 1 performance with transfer speeds up to 5Gbps across all three USB-A ports. The integrated Gigabit Ethernet controller provides full 10/100/1000 Mbps connectivity with support for advanced networking features including Wake on LAN (WoL), Jumbo Frames up to 9KB, and VLAN tagging.
The hub implements Overcurrent Protection (OCP) to safeguard connected devices, with shared power distribution up to 4.5W total across all ports. This power allocation supports typical USB peripherals including external storage drives, input devices, webcams, and audio accessories without requiring supplemental power.
Relevant factors for this section include Host Interface, Total Number of USB Ports, Number of USB 3.0 Ports, Number of Network (RJ-45) Ports. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.

IT professionals can deploy these hubs as standardized connectivity solutions across their organization, ensuring consistent peripheral and network access regardless of laptop model.
Common deployment scenarios include conference room setups where presenters need both USB peripherals and reliable Ethernet connectivity, remote workstations requiring stable network connections for VoIP or video conferencing, and temporary work areas where users need to quickly expand their laptop's connectivity without complex setup.
Mobile Office Solution
Provides complete connectivity for professionals working from multiple locations, combining storage access, input devices, and secure wired networking in one travel-ready device.
IT Department Standard
IT teams can standardize on this hub for consistent connectivity across diverse laptop models, simplifying support and ensuring all users have access to essential ports regardless of their laptop's native capabilities.
Physical Profile
Measuring just 4.4 inches in length with a slim 0.8-inch profile, the hub occupies minimal desk space while providing substantial connectivity expansion. The compact dimensions make it ideal for crowded workspaces or travel bags. The aluminum construction provides both durability and effective heat dissipation during continuous operation.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 0.80" (20.32 mm), 1.40" (35.56 mm), 1.40 oz (39.69 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.

User Manual
FAQ
Does this USB hub require an external power adapter?
No, the ST3300G3UA operates entirely via bus power from your computer's USB port. It draws up to 4.5W of shared power across all connected devices, which is sufficient for typical USB peripherals like keyboards, mice, webcams, and most external storage drives. For power-intensive devices that exceed this allocation, you may need a separately powered hub.
What operating systems are supported by this USB/Ethernet hub?
The hub supports Windows 7 through Windows 11, Windows Server 2008 R2 through 2022, macOS 10.6 Snow Leopard through macOS 13 Ventura, ChromeOS, and Linux. Most modern operating systems include native drivers for both the USB hub and Gigabit Ethernet components, though downloadable utilities for advanced features are available for Windows and macOS.
Can I use the Gigabit Ethernet port while also using all three USB ports?
Yes, all ports operate simultaneously. The hub manages bandwidth allocation between the USB 3.0 ports (up to 5Gbps total shared bandwidth) and the dedicated Gigabit Ethernet connection (1000 Mbps). In typical use cases, you can connect storage devices to USB ports while maintaining full Ethernet performance for network-intensive applications.
What security features does this hub include?
Beyond the physical Overcurrent Protection, the hub includes downloadable utilities for enhanced security: MAC Address Changer allows you to randomize your network identity, USB Event Monitoring logs all connection activity, and Wi-Fi Auto Switch automatically prioritizes wired Ethernet when available. These tools help maintain network security and privacy in various deployment scenarios.
Is this hub suitable for connecting external hard drives or SSDs?
Yes, the USB 3.0 ports support transfer speeds up to 5Gbps, making them suitable for most 2.5-inch external hard drives and SSDs. The bus-powered design provides sufficient power for typical portable drives, though some high-performance or multi-drive enclosures may require supplemental power. The hub's aluminum housing also helps dissipate heat during extended data transfers.
What warranty and support does StarTech.com provide for this product?
StarTech.com backs the ST3300G3UA with a 2-year limited warranty covering defects in materials and workmanship. Additionally, they provide free lifetime technical support available 24 hours a day, 5 days a week with multi-lingual assistance.
