From be4925b018b3c398d2775826091c693f214630a8 Mon Sep 17 00:00:00 2001 From: Przemo Firszt Date: Tue, 15 May 2012 19:32:26 +0100 Subject: [PATCH] HID: wacom: Add speed setting for Intuos4 WL Add option to change reporting speed for Intuos4 WL. The option is only internal to the module, but it will be extended to allow control over sysfs, as it is already implemented for Graphire.
