From a2063172ccafb5e7748a3b6719df8ac68ec89060 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Michal=20Mal=C3=BD?= Date: Mon, 24 Sep 2012 12:13:29 +0200 Subject: [PATCH] HID: hid-lg4ff: Set absolute axes parametes on DFP MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The lg4ff driver doesn't fill the "input_absinfo" struct so it is left with default values. Applications with rely on information in this struct therefore do not work correctly with the wheel. Other Logitech wheels probably need this fix too, but again I do not have enough information to write it.
