This reverts commit 1b2faaf7e219fc2905d75afcd4c815e5d39eda80. The Intuos4 series presents a bug in which it hangs if it receives a set feature command while switching to the enhanced mode. This bug is triggered when plugging an Intuos 4 while having a gnome user session up and running.
Signed-off-by: Benjamin Tissoires <[email protected]> Signed-off-by: Aristeu Rozanski <[email protected]> --- Hi, This patch is on its way upstream (it has been submitted to the list): http://www.spinics.net/lists/linux-input/msg31843.html I already received a complain from Bastien that his Wacom was broken in F20, so having this in F20 and rawhide would help the Intuos 4 users. The regression has been introduced in the kernel v3.12, so F19, F20 and rawhide are impacted.
