Overview

The USB-C port on the Plugable USBC-7IN1 is for USB-C Power Delivery pass-through only. It is designed to accept power from a USB-C charger and pass that power to the connected laptop. It does not support USB data transfer, video output, or connection to USB-C peripherals.

Why this happens

USB-C describes the connector shape, not the features supported by the port. Some USB-C ports support data, some support video, and some support charging only. On the USBC-7IN1, the USB-C port is a charging-only Power Delivery input port.

What to use instead

If you want to connect USB devices such as storage drives, keyboards, or other peripherals, use the hub’s USB-A data ports. The USBC-7IN1 provides two USB 3.0 ports for data, and the USB-C port is reserved for power input only.

Summary

If a USB-C device is not recognized when plugged into the USB-C port on the USBC-7IN1, this is expected behavior. That port is for charging only and does not pass data
