Here's a quick and dirty test with USB, and a bunch of DS18S20s:
amd64:/home/paul/owfs # owserver -u -p 3000
amd64:/home/paul/owfs # for x in `owdir -s 3000` ; do owread -s 3000
$x/temperature ; done
Data error on /bus.0/temperature

Looks like one "85" in the mix.
Serial seems to work as well (separate test).
