ZBook 15 G3 & HP Thunderbolt Dock G2 w/USB Connected Web Camera Performance Issues

[HMBMartin3]

I've been having video performance problems with an HP Webcam HD 4310 on my ZBook 15 G3 through an HP Thunderbolt Dock G2.  Laptop BIOS, Windows Drivers, Thunderbolt 3 firmware and Dock G2 firmware have all been updated to the latest, as of Jan 9th, 2019.

When the camera is connected directly to the Thunderbolt Dock G2 via USB, the video cuts out or stops (depending on which application is using the camera) for all applications using the camera.  Even the camera management tools.  It must be the dock due to the fact that connecting the camera directly to the laptop's USB socket eliminates the problem.

It would be desirable to have the camera connected to a KVM switch which has USB connectivity to the G2 dock. This allows me to switch between my Linux workstation and my laptop running Windows 10.  But, with the video performance problems through the G2 dock, I have to manually swap it between the two.
