Comment 13 for bug 660664

are you using the xp drivers? are you putting the sys and inf files in the same directory?

Are you doing this all from command line? You could always apt-get ndiswrapper-gtk to make sure everything is where it needs to be

you can also try installing the next version

these are rpm, but you can convert them using alien
