Samsung say that they will not release a driver until Windows 7 release date (23 October)
I actually got it working! I downloaded the Vista driver, did a right-click "Troubleshoot compatibility", and worked thru that wizard, selecting to install with "Vista SP2" compatibility mode. Once I did that, it installed w/o giving me any "won't work on this version of Windows" message. And so far, the driver has worked fine! Try it!
