Which is actually the same reason QUADTAP was added originally... are we entering a recursion here? ;-) I tend to agree with Dmitry - without a clear usage, it makes sense to instead wait to see which comes first - a five-finger usecase or a true MT device that everybody can afford. > Similarly, I work with many touchpads from different vendors, some of > which do actually provide 5 independent finger coordinates.

I would say yes. ;-) Cheers, Henrik -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
