I have been running with the Multi-Display adapter (USB 3.0 to DVI) for several months with no issues, but as of last week, either some update or other culprit has stopped powering the Plugable DisplayLink adapter (no blue light) from the Surface Dock. I have rebooted, reseated, switched to all the other USB ports on the dock, but no power. However, when I plug it into the only one, highly valuable, USB 3.0 port on the Surface Pro 4 itself, it works fine. I would like to know how to get it to work again on the Dock with ample USB 3.0 ports rather than suck up the only available port on the Surface Pro 4.
NOTE: I have verified all the USB 3.0 ports work on the Dock using other devices.
