Check the device manager and see if there'e a driver installed or an error icon. Check the manufacturers website for a 7 compatible driver. If there isn't one and you're running 7 Professional, business or ultimate, you can try downloading the XP compatability package and try running the software on that. If it's already installed, uninstall the driver, and the smartboard software and then re-install them with the virus checker/security package disabled. Prior to that, do what everyone should do, i.e. wiggle cables, listen to see if noises are made when the USB leads plugged in etc. Sounds stupid I know, but 95% of whiteboard problems at our place are cured by checking the things plugged in properly. If all else fails, hassle whoever it was that decided to upgrade to 7 without checking whether or not your hardware is compatible first.
