Why does the 6176 need its own compatible string, when the two 6352s and the 6165 on the zii-devel-b don't have one? And the DIR 665 has a 6171, which does not have a compatible string of its own. The clearfog actually has a 6176, and it seems to work fine without a compatible string. > You as driver author should know that the .data pointer is vital to your > driver Exactly, so if i ask why is it needed, maybe you should stop and think for a while. > you even recently accepted another model that conflicted with > my patch. And think about that also, and you will find the 6390 family, who's first device is 6190, is not compatible with the 6085, and so needs a different compatible string. Andrew
