USB 3.0 Gigabit adapter with pass-through

The StarTech USB31000SPTB adds a 10/100/1000Mbps RJ45 port and a USB 3.0 pass-through to any laptop or desktop with a USB-A socket. It draws power from the bus and uses the ASIX AX88179A chipset for native driver support on Windows 7 and later, macOS 10.14 and later, Linux kernel 2.6.25 LTS and Chrome OS. The compact 5 x 1.4 x .7 inch enclosure weighs 1.5 oz and includes a driver CD.

Wired throughput and port headroom

The Gigabit Ethernet link negotiates at 10, 100 or 1000Mbps with full-duplex and Auto-MDIX crossover correction. The integrated USB 3.0 pass-through port preserves the host socket for a mouse, flash drive or other peripheral while the adapter is connected. Wake-on-LAN and VLAN tagging are supported for managed network environments.

Build integration and constraints

The adapter connects via a USB 3.0 Type-A male plug and requires an available USB-A port on the host. It operates over standard Cat5e or better cabling up to 100 metres. The package supplies the adapter, a driver CD and an instruction manual; no external power supply is needed. Buyers who need multiple Ethernet ports or a USB-C host connection cannot use this model.

Questions about this item

Will the USB 3.0 passthrough port still run at SuperSpeed when the RJ-45 link is at 1000Mbps?

Yes, the adapter uses a VIA VL811 hub for the USB 3.0 A female port and an ASIX AX88179 controller for Gigabit Ethernet, so both operate independently at full 3.0 bandwidth.

How can I confirm the adapter has negotiated a 1000Mbps full-duplex link after plugging it in?

Check the link LEDs on the RJ-45 connector and verify the OS network status shows 1Gbps full duplex; the ASIX AX88179 supports IEEE802.3ab auto-negotiation and Auto-MDIX.

Does the package include a driver CD for Windows 7 or must I download the driver separately?

The box contains the adapter, a driver CD, and an instruction manual; the CD provides drivers for Windows 7 and later, while macOS 10.14+, Linux kernel 2.6.25+ LTS, and Chrome OS use in-box drivers.
