If you get a working update, please also remove the "unknown" stuff from the returned string. We must not return anything we are not entirely sure about, and the strings must never change when something becomes "known" in the future with some kernel/driver/sysfs update or anything similar. In all such cases we better return nothing, than some random stuff we can not keep reasonable stable. Thanks, Kay
