Fiddled around with similar issue some time.
In my case the USB Device ( 3shape D800 Scanner ) got installed as virtualblabla-Device after playing around with some USB network sharing tools.
TLDR: If you run into this it may help if you try to find out which driver is currently installed for the connected scanner ( open device manager > USB Controllers, plug/unplug the scanner-usb cable to see which Device is going on and off ) and then while connected again right click uninstall this device.
Then unplug/reconnect scanner and it might install correctly again as in my case. here we go 2014 problem maybe solved
cheers
