+ * Translation of scancodes to keycodes. We set them on only the first
+ * keyboard in the list that accepts the scancode and keycode.
+ * Explanation for not choosing the first attached keyboard anymore:
+ *  USB keyboards for example have two event devices: one for all "normal"
+ *  keys and one for extra function keys (like "volume up", "make coffee",
+ *  etc.). So this means that scancodes for the extra function keys won't
+ *  be valid for the first event device, but will be for the second.
