So I tried the same instructions on Linux Mint.
Here is a fresh install without any display-link drivers:
Code:

Notice the usb is first recognized as DisplayLink [1-4.7.2.2] and then later, within that USB chain, it recognizes a storage device [1-4.7.2.2:2.0] ... I believe that is the core of the main error. How to fix?
After installing driver ...
Code:

The NUC only has USB 3.0 ports - the device is USB 2.0 , maybe I am incorrectly assuming backward compatibility?
