Please note that the hub's PD-IN port is for power input only and does not support downstream devices. The other USB ports are for data transfer. If the device does not function properly, Please try the following troubleshooting steps:

• Disconnect the hub and all connected devices from your laptop. Wait at least 5 minutes, restart your laptop, and reconnect the hub.

• Connect the USB device directly to your laptop to check whether it works properly.

• Try another USB-A or USB-C device to determine whether the issue is specific to one device.

• Connect the hub to another laptop to check whether the issue persists.

If all of the steps above cannot help you locate and resolve the problem, please contact Anker Customer Support for further assistance. Briefly mention the steps that you’ve already tried for a faster solution.
