USB-C Hub with Gigabit Ethernet

The LUOM ULC28 adds three USB 3.0 ports and a wired RJ45 network connection to any USB-C or Thunderbolt 3 laptop. It suits professionals who need reliable Ethernet and extra peripherals without installing drivers. The aluminium housing aids heat dissipation during sustained transfers.

5 Gbps USB 3.0 and 1000 Mbps LAN

Each USB 3.0 port delivers up to 5 Gbps for flash drives, external disks or input devices and falls back to USB 2.0 speeds when required. The Gigabit Ethernet port negotiates 10, 100 or 1000 Mbps for stable wired networking. Both interfaces operate simultaneously without an external power supply.

USB 3.1 Gen 1 Interface Limits

The hub relies on a single USB 3.1 Gen 1 upstream link, so total bandwidth across the three USB-A ports and the Ethernet controller is shared and capped at 5 Gbps. Heavy concurrent disk and network traffic will contend for that ceiling. The adapter functions from 0 °C to 70 °C in non-condensing humidity.

Questions about this item

Will the hub work with the USB 2.0 flash drives I still use?

Yes, the USB 3.0 ports are backwards compatible with USB 2.0 devices, so your existing flash drives will function normally at their rated speed.

How can I confirm the Gigabit Ethernet link is running at full speed after I plug it in?

The adapter has Power/Activity LEDs; a lit activity light indicates a live 10/100/1000 Mbps connection, and your operating system's network status will show the negotiated 1000 Mbps rate.

Does the package include a USB-C cable or do I need to supply my own?

The hub has an integrated USB-C connector that plugs directly into the host, so no separate cable is required; only an Ethernet patch cable and any USB-A peripherals need to be provided separately.
