Hi Stuart,

thanks, I tried to look it up better this time and saw this already at
the linuxtv wiki. Also found a reasonable picture, but not good enough.
At least no 16 pins KS007 so far.

We must identify the IR controller chip.

Guessing doesn't help any further.

The only thing you can blindly try, see the v4l-wiki about remotes, is
to start with a mask of 0x0 for key codes and hope something happens on
the GPIOs.

Cheers,
Hermann
