From 7dc39b55ecc16a4db44c820263c73a60fc750b27 Mon Sep 17 00:00:00 2001 From: Simon Wood Date: Thu, 10 Oct 2013 08:20:13 -0600 Subject: [PATCH] HID: lg: fix Report Descriptor for Logitech MOMO Force (Black) commit 348cbaa800f8161168b20f85f72abb541c145132 upstream. By default the Logitech MOMO Force (Black) presents a combined accel/brake axis ('Y'). This patch modifies the HID descriptor to present seperate accel/brake axes ('Y' and 'Z').
