Looks like the packages are installed. I've tried to delete and re-add 1-wire, but womb is still barren - no children at all. The update gave me some errors that don't look like they concern 1-wire, but then again who knows? My 1-wire adapter is still showing unregistered after several hours. It had registered before, but I don't know how long it took.
