The Whirl did not ship with any software so we went to the Smartfish website and grabbed the appropriate driver there.
The driver includes the basics like switching the primary and secondary mouse buttons, double click speed and choosing various mouse pointers. The new driver enabled 4 way scrolling and selectable DPI settings. The DPI settings are 400, 800, 1200 and 1600 DPI. This is much better then originally being limited to 800 DPI. These features made a noticeable improvement over the default windows settings without the driver.
