I now have the remote, I tried using xinput test and most keys seems
to be working fine except the special buttons like subtitle, colors,
x, l1... Im not sure if they are not being mapped because they don't
have any representation or there is something wrong in the parser
itself (Bastien do they used to work for you?). Also got a problem on
suspend but I will have to reproduce it again to see if it is because
of the new driver or not.
