This patch adddresses two issues: - some model also has debounce packets, but with a different signature than v3. Now we just check debounce for all v2 hardware. - due to different scanning methods the hardware uses, x and y ranges have to be calculated differently. And for some specific versions, we can just see them as custom-made, so set {x, y} the same values as Windows driver does.
