Just a note. At least myself and pow didn't uninstall the previous drivers before installing the s-seven drivers. I was going to, but when I found out that pow didn't, I wanted to try that first to match his results. They probably work well after uninstalling as well, but they seem to work great without uninstalling.
I did [briefly] check out the .inf file to see what it had in there, and there appeared to be a bunch of information on cleaning thigns out first, but I could be horribly wrong about that. And I'm not at home to post a verification, so this is just from memory.
Just wanted to let people know that at least some of the great results were obtained by _not_ uninstalling first. These are some weird drivers, and it definitely appears that some form of magic is at work here. Maybe it has to be a certain phase of the moon...
