Experts answer:Uninstall the driver, according to product instructions to re-install the driver, If not for a USB interface to try again. I have installed other types of camera, in an interface change after the installation was successful. If your operating system is WINDOWS98, it does not support USB devices, you must first install the USB driver processSequence. WINDOWS2000 later version can be installed to support USB camera device driver. After the installation, to check the menu on the preview function.
