First try using a different USB port then try uninstalling the driver from your previous USB audio interface, some of these USB interfaces use the same USB controller and windows attempts to use the driver that is already installed. I had this problem when I used a Line 6, and a Yamaha THR10C, and had a Behringer USB Mixer previously installed. They all seemed to use a Steinberg USB controller, I had to uninstall the Behringer driver to get the others to work properly
