There are several strange hardware devices like this that are popping up and need some sort of configuration that isn't provided by the kernel - motion sensor physical orientation is another one. I hate to be the one to suggest a new HAL (http://www.freedesktop.org/wiki/Software/hal/) but it would be nice for the hardware database libraries to be somewhat coherent. _______________________________________________ wayland-devel mailing list wayland-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/wayland-devel
