So the dock itself can apparently be detected, but not by DisplayLink's driver software. When the dock is connected to the Microsoft Surface Pro/Windows 10 Pro device, the firmware updater detects the dock, displays the proper latest firmware version v4401, and allows the firmware to be flashed. It has worked fine for weeks, but suddenly whenever I boot up in the morning and connect the USB 3.0 port, everything works except the monitor.

Incidentally, the Targus site has a firmware download for the ACP70USZ dock. I am using a Targus Universal USB 3.0 DV Docking Station ACP70USZ with a Dell XPS 13 (元21X). I tried this same Targus dock with another Windows 7 machine, and it detects it just fine at the First Connect stage, and it also ends up showing properly in Device Manager. Skipping that part of installation and rebooting doesn't show the USB Display device in Device Manager. Connecting the USB 3.0 cable simply waits forever. Upon installing the DisplayLink v7.9M0 driver, it comes to the point where it says to connect the dock for First Connect configuration.

This device won't detect DisplayLink video output at all. Operating System: Microsoft Windows 10 Pro (fully updated and upgraded from 8.1 Pro)
