As a rule, USB devices need to be plugged in before you install the drivers. You don't need to reformat the computer to reinstall the hardware, just uninstall the hardware drivers from Windows, using Control Panel > System > Hardware > Device Mangler.
As far as I know this is Behringer's first foray into sound cards, so teething problems are to be expected, I guess... :/
