Default DisplayLink only works when PowerPoint launched?

I have a Lenovo Yoga Laptop (720-13IKB) running Windows 10. I'm using a DisplayLink hub to connect to two monitors and a number of USB devices (microphone, camera, bluetooth keyboard and mouse). I also have two devices plugged into power in the hub.

The DL adapter has been working fine until recently when the video feed to the monitors stopped working...except when I launch a PowerPoint. Otherwise, all functions of the hub work fine (camera, microphone, etc). This is what I've tried:
  • Made sure I was running the most current DL driver
  • Updated windows and all other drivers and software
  • Used the display settings to detect the monitor (no monitor detected)
  • Restarted and shut down with adapter connected and unconnected
  • Power cycled the hub

When I look at the device manager and look at USB controllers I see one listed as "Unknown USB Device (Device Descriptor Request Failed)." When I click on it, it says Windows has stopped the device because it reported problems (Code 43).

Any ideas or suggestions?
