I am not sure... that BTN_TOUCH - look slike it works off a single flag reported by hardware. You porobably do not need to change it. Try loading mousedev module (after adding input_sync back to your driver) - it provides cooked PS/2 protocol to userspace - it should bind to your driver. Then you can use GPM or X (read from /dev/input/mice) to test the touchscreen and see if you have issue with double clicks. -- Dmitry - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
