I have 3 laptops, each connected to different DisplayLink USB 3.0 docks, that are randomly being disconnected from display and Ethernet services supplied through their dock. This disconnection is happening randomly every 10 minutes to 2 hours. They are each displaying the exact same behaviors...the external/attached monitors will freeze and the Ethernet service will drop, but the laptop itself continues to work (without network services). Unplugging power from the dock and then plugging the power back in allows the dock to reconnect and restores display & Ethernet services.
We have the following laptop/dock combos:
--2 Lenovo Thinkpad S1 Yoga 12's; 1 connected to a Lenovo USB 3.0 Dock and the other connected to a Toshiba Dynadock U3.0 dock
--1 Dell ATG Rugged laptop connected to a Dell USB 3.0 Dock.
I have focused my troubleshooting on the Yoga that is connected to the Dynadock U3.0.
I noticed that each time this event occurs, an event is logged in the Event Viewer stating that "the device dynadock u3.0 is offline due to a user-mode driver crash." (event ID: 10111)
I have tried all the steps suggested here with no luck:

I have attached the results of the Display Link Support Tool, run with advanced logging for your review.
