From 9fb6de1b0bf4ec11573b76059da3c3b39ac7f2ff Mon Sep 17 00:00:00 2001 From: Ville Ranki Date: Thu, 15 Sep 2016 15:31:27 -0700 Subject: [PATCH] Input: joydev - recognize devices with Z axis as joysticks Current implementation of joydev's input_device_id table recognizes only devices with ABS_X, ABS_WHEEL or ABS_THROTTLE axes as joysticks. There are joystick devices that do not have those axes, for example TRC Rudder device. The device in question has ABS_Z, ABS_RX and ABS_RY axes causing it not being detected as joystick. This patch adds ABS_Z to the input_device_id list allowing devices with ABS_Z axis to be detected correctly.
