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.
