There is no Vista driver for it, but you should be able to get the XP one working.
There seem to be two ways:
1 ) Yes, it says Windows 7, but for your purposes there's no difference:
2) Download the EXE version. Right-click it in Explorer, select Properties, access the Compatibility tab, and select Windows XP SP2. OK that and run it. Reboot afterwards.
BTW, if you have Vista x64, I think you're out of luck but I'm not sure. If you have x86, you should be fine.
