Overview — CU009-A | USB 3.0 Gigabit Ethernet Adapter
The CU009-A USB 3.0 to Gigabit network adapter is a compact, high-performance LAN conversion module built around the WCH CH398 controller. It extends 10/100/1000 Mbps wired network connectivity for desktops and notebooks. It connects to the host via a standard USB port and requires no internal disassembly for deployment. A dedicated installer simplifies driver setup and configuration. The RJ45 port supports automatic link negotiation; in full-duplex mode the theoretical bidirectional throughput reaches up to 2 Gbps for a stable high-bandwidth wired link. Integrated power management logic reduces power draw and extends battery runtime on portable devices.
This NIC automatically detects the connected switch and negotiates the link rate, supporting 10Base-T, 100Base-TX and 1000Base-T. Under full-duplex operation, the corresponding link speeds are: 20 Mbps bidirectional for 10Base-T, 200 Mbps bidirectional for 100Base-TX, and 2 Gbps bidirectional for 1000Base-T. With its small, portable form factor, the adapter can be moved easily between hosts without occupying much desktop space. It works with devices equipped with USB 2.0 or USB 3.0 ports, including Windows ultrabooks, Chromebooks, MacBooks, regular laptops and desktops. A USB 3.0 port is recommended to achieve full rated performance.
