1. Connect a USB flash drive to the faulty dock. Will it appear on the system?
2. Connect Ethernet cable and disable Mac Wifi to verify if network function still operates on the device.

I had the same issue with that UGREEN Model.

I've tried the USB, and my Mac does not recognize it. What should I do?
