GPS USB Mac Drivers

I have been trying to get a driver from www.ftdichip.com/FTMacDriver.htm
to enable me to use my GPS USB mouse on my Mac Mini. Google search for FTMacDriver brings up pages of references to the site but when clicked as an address it always comes up as not found. Any suggestions or has anyone got the driver so that I could download it?
Thanks, Ian
