You probably want to boot with i8042.debug (or activate it via /sys/module/i8042/parameters/debug), load psmouse module and see what kind of response you are getting from the device. Also, have you tried forcing touchkit protocol by doing: echo "touchkit" > /sys/bus/serio/devices/serioX/protocol Thanks. -- Dmitry -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
