From 921990b7046ab4fb523cbccc5bce2c921762232d Mon Sep 17 00:00:00 2001 From: Henrik Rydberg Date: Tue, 31 Aug 2010 21:56:24 -0400 Subject: [PATCH] HID: magicmouse: Adjust major / minor axes to scale By visual inspection, the reported touch_major and touch_minor axes are roughly a factor of four too small. The factor is approximate, since the protocol is not known and the HID report encodes touch size with fewer bits than positions. This patch scales the reported values by a factor of four.
