For our customers we are constantly testing useful accessories. Recently we tested the Microsoft Dockingstation USB-C Travel Hub. It's a stylish and cool device, yet we have a major issue on several HP computers: anytime between 2 and 8 minutes after plugging it in into the Thunderbolt port, the Ethernet connection drops - the operating system does not even see the NIC anymore and the "Surface Ethernet Adapter" is show as disconnected in Device Manager (View > Show hidden devices).
We were able to reproduce the problem with multiple HP devices having a Thunderbolt port. Other peripherals attached to the Travel Hub (like headphones on the USB-A port) continue to function.
We tested with W10 1909 (Build 1198) 64-bit edition, and have manually updated the Surface Ethernet Adapter Driver to the newest version available from theUpdate Catalog (10.14.117.2020). We were unable to find useful information in Event Viewer, or any other place.
Does anyone in the tech community have some hints on further troubleshooting or ruling out a generic Windows issue with Thunderbolt?
