How they will agree on which one to set? On the other hand I do not want psaux to give me only exclusive access as I have had emough of GPM repeater feeding X feeding Y ... etc. It does not support active multiplexing controller (4 AUX ports) which becomes quite common and is the only sane option when you have several mice of different types. Also I do not see where the code makes sure that it does not bind to keyboard's port (so keyboard driver has to be loaded first). I think the right way is to fix the issues with psmouse driver and use input system to tie all hardware together. -- Dmitry - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
