Thanks for posting the update, I was just about to do so myself :).
I want to reiterate that any unwanted effects of Zadig can be undone and the driver removed by persistently looking for 'libusb-win32 devices' appearing in Windows Device Manager (WDM) as you attach your board and then selecting both 'uninstall device' AND 'uninstall driver' , then after it seemed to complete ,disconnecting and reconnecting your board to see if it reappears , if so, repeat until it does not. You have to to this seperately for every USB port you ever connected to.
Note - when you expand the drop down for 'libusb-win32 devices' you will see it twice as in 'interface 0' and 'interface 1' , so repeat for both.
Note - on my machine 'libusb-win32 device' which starts with an 'L' was as appearing between Keyboards and Memory devices in WDM rather than under USB where you might be thinking to look for a USB device you just plugged in .
I just operated on a similarly affected colleagues PC and both machines are now doing well lol !
