I'm now unable to get the Ethernet adapter to work with anything but the 7.2 driver, 7.2 seems to install some firmware update to the dock. Now reverting to anything previously refuses to allow the Ethernet adapter to be enumerated correctly. It comes up as an invalid device with anything but the 7.2.

Tried: 7.2 M0, 7.1 M1 & 7.0 M3, now only 7.2 M0 enumerates the USB (with awful performance).

The Ethernet down speed is now capped at about 50KB/sec.

I've also made sure (very important for video performance) in device manager, ensured that the USB 3 dock is enumerated correctly.

Within Device Manager, select "VIEW DEVICES BY CONNECTION" and expand it until you find the Intel Extensible USB 3.0 driver. (If your laptop/device uses this chipset)

Make sure that the Video and Ethernet appear under a USB 3.0 hub. Otherwise you get blurry screens, and poor Ethernet performance when your screens are busy refreshing. I had to refresh my USB 3.0 drivers previously to fix this.

My temporary fix, plug in a USB 2.0 Ethernet adapter into the dock until this is sorted out, I mostly use my X1 Carbon for Internet work, so 100Mbps is faster than my internet connection anyways. Internal file backups and copies, still painful.
