I just wanted to say that I have tested the patch at

https://patchwork.kernel.org/patch/765792/

and (as a simple user) I find it great !
It works perfectly on my kubuntu 11.04
(after I chmod the files in /sys/class/input/input13/led to read-write)

A beginners' question: the device can be accessed by, for instance

/sys/class/input/input13

What is the best way to find out which number it is (here 13) ?

Thanks again for this great patch, for us, Intuos4 users.
