Hey folks. Bought this mouse the other day and thought id throw the driver up in case somebody out there needs it. This driver is zipped from the manufacturers floppy to which it came on. All you have to do is go into "my computer" then open the "a" drive and click the setup file. Have no worries this is exactly what it says it is. I havent tried it on XP i just added here the operating systems the box says its compatable with. Enjoy!!
