I purchased the CSV-1560 and want to use it for a laptop. The dock is connected to power, HDMI and USB 3.0 cable that goes to a hub for all my devices. When connecting the laptop in this configuration via USB C charging and HDMI work, however, no USB devices conencted to the hub is recognized on the laptop. If the cable going to the dock is directly connected to the laptop, it works. What is the problem with the dock?
