My comment was for other users future reference - no board modification is required! (I assume you board is damaged somehow). The attached schematic snippet shows the functionality.

I actually toke a closer look at the schematics and at my board and found out that the inverter (U23) was broken, as it is always outputting 3.4V regardless of it's input, therefore keeping U22 always disabled.
