My guess is that Windows update rewrote your chipset drivers (Microsoft does that sometimes with their drivers) and now your USB 3 port is unable to correctly work with USB 2 devices.
You might want to try to find chipset or specifically USB drivers of the manufacturer of your computer or motherboard - usually directly from Intel or AMD website and reinstall those to replace the Microsoft ones.
Also, if your computer has USB 2 ports (the black ones, not the blue USB 3) try to connect Minilab to those and see if it works.
And according to the thread you mentioned, Minilab might have created and left ghost entries. So you might want to try out the following:
- disconnect the Minilab
- click on "View-> Show hidden devices" in Device Manager menu
- in Device manager tree find all instances of Minilab (most probably under "Sound, video and game controllers" but I'm not sure, I don't have Minilab - wanting to buy but still in doubt) and right click and Uninstall for all of them
- restart the computer
- connect the Minilab again
Hopefully it will help. You might want to try combinations of both solutions - disconnect Minilab, remove ghosts, reinstall chipset drivers, restart, connect.
