Downstream bug report:

What happens when using a StarTech device (Product ID: USB3SDOCKDD) with either the DisplayLink driver from StarTech's website (1.1.62), or the latest from DisplayLink's website (1.2.65), is when I attach the USB 3.0 cord to the USB 3.0 port on my laptop for the first time after a reboot, open arandr, open the StarTech.sh file, and click Apply, the Dell E2414Ht monitor VGA connected on the left is the primary and the laptop display is the secondary on the right.
However, if I disconnect the USB cord, then reconnect, and then re-apply the file, I get a pop up noting:
