Uploader Notes
This is a whole bunch of drivers for USRobotics modems, even hard-to-find ones such as the USR Sportster Flash driver. They are updated drivers to those orginally released. They came straight from USR, but don't seem to be held on the websites any more. (Note Used in the UK, might not work in USA etc.)
