How to use

Connect the Aukey CB-C89 to a compatible device using its USB-C plug. Once connected, the hub enumerates connected ports and devices; plug in an Ethernet cable to enable wired network access, connect an HDMI cable to an external monitor or TV for video output, and attach USB peripherals or external storage to the available USB ports. Ensure the host device supports USB-C peripheral mode or DisplayPort Alt Mode if using video output. Drivers are usually provided by the host operating system; check system settings if a device is not recognized.

Recommendations

For stable network performance, use a high-quality Ethernet cable and a Gigabit-capable router or switch. To achieve the best video output, use HDMI cables rated for 4K at the intended refresh rate and verify that the host device supports 4K output over USB-C. Avoid excessive bending of the hub cable and keep vents unobstructed if the hub has passive cooling slots.
