According to the information contained within the inf file, this driver is used for Windows 2000/XP/2003/Vista, other documentation I read said that it works with the 64bit systems too. I do not have 64bit installed on my computer, although I could for testing purposes...
Check out the new drivers I just uploaded... someone needs to try them out Mac users and Linux... I could try linux I guess... can't help on the Mac though.
