Dear Cascardo and Dmitry,

Thank you for the hint with the hidraw. I was briefly looking at this
in the beginning of the project, but I found it was a bit too raw for
my purpose. Well, I was wrong...

Based on the example in the Documentation
(http://ns3.spinics.net/lists/linux-input/msg14216.html), together
with the patch for HIDIOCSFEATURE
(http://choon.net/forum/read.php?21,19545) and the same for
HIDIOCGRAWNAME I was able to first write a small test program and
later last night to actually build it into my software project.

Thank you very much the effort in helping me with this.

Take care,
David
