It doesn't use an input interface either but I don't see a good place for an accelerometer that uses sysfs only. It works well, is a relatively recent chip and a clean dirver. But this is all I can provide. > Best regards, > Alexander > -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
