StarTech 5G3AGBB-USB-A-HUB Portable USB Expansion Hub w/ GbE
Overview
The StarTech 5G3AGBB-USB-A-HUB is a compact, portable USB 3.2 Gen 1 hub that adds three USB-A ports and a 2Gbps Gigabit Ethernet port to your system. This unit is designed for environments where you need to connect multiple peripherals or network devices to a single USB port, such as a workstation, a mobile surveillance cart, or a point-of-sale terminal. Its support for Wake-on-LAN (WOL), Jumbo Frames, and VLAN Tagging makes it suitable for network-intensive applications. The 5G3AGBB-USB-A-HUB can be powered via USB bus or an optional Micro USB connection for increased power delivery.
Compatibility
This USB hub is compatible with systems running Windows, macOS, Linux, ChromeOS, and Android. It connects via a standard USB Type-A host connector, making it plug-and-play with most modern computers and laptops. The integrated RJ45 Ethernet port supports 10/100/1000 Mbps networks and is backward compatible with older Ethernet standards.
Installation Notes
The hub supports bus power from the host system, drawing under 13W via standard USB 3.2 Gen 1 (5 Gbps). For applications requiring higher power delivery to connected USB devices, an optional 5V Micro USB power source can be connected. The integrated Ethernet port supports Jumbo Frames up to 9K, which can improve network throughput for large data transfers by reducing the number of packets processed. VLAN Tagging (IEEE 802.1Q) allows for network segmentation, enhancing security and traffic management in enterprise environments.
