As of 0.9.2 (or earlier) mode2 does not work with this kind (lirccode)
of driver. So it really makes no sense here (In upcoming 0.9,3 mode2
supports all kinds of drivers).
The corresponding tool here is ir-keytable(1). It can be used to debug
the kernel decoding, and that is what's used by the devinput driver. If
ir-keytable displays the buttonpresses you should be fine (using the
correct devinput config file). It not, you need to fix the kernel side
of it. The LIRC devinput driver is just a bridge to the kernel decoding.
Cheers!
