Everything said above is definitely right, and since I see libsolid 
mentionned... I'd just like to let you know that you're using 
Solid::GenericInterface in your code, which is fine as an interim solution 
(it's there exactly for that purposed) *BUT* automatically makes your code not 
portable at all.

In your case, with the current timing, it means that your code there should 
stop working at some point if we swap the backends. So be aware of it, if 
there's need for some other facilities, I'm fine discussing them to maybe 
slightly extend the libsolid API to provide what you need for this kded 
module. From what I see you need to:
 - locate input devices;
 - on those input devices you need to know the driver to use;
 - and also the exact type of input device.

Is it correct?

I'm not fully clear on the type of input devices though... I see mentionned 
stylus, pad, eraser and so on, but that doesn't tell me much.

Regards.
