I recently purchased a Plugable UD-3900PDZ for use with a Surface Pro 5 (model 1796) running Windows 10 1809. As this model of Surface Pro does not have a native USB C port, I also purchased a Surface Connect (Surface’s proprietary power connector) to USB C cable (this one). Finally, I installed the latest DisplayLink 9.3 M3 driver found here.
Unfortunately, when I connect the Surface Pro to the UD-3900PDZ, none of the devices attached to the docking station are recognized by Windows (wireless mouse with USB transceiver, USB keyboard & 3x HDMI monitor connections). However, the PD component connects successfully, as the Surface Connect LED light is activated, and the battery charging icon is displayed in the Windows Notification Center.
I’m hoping that someone can offer some assistance with this issue. Thanks!
