Bugzilla: N/A
Upstream-status: Sent upstream
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.

Hi Aris,
actually, you bisected the bug, so can I consider that I have your signed-off-by?
Cheers,
Benjamin
