Mostly The Links, but the DS9490R USB thing in one of my setups.  I
also have the regular serial adapter (DS9097U), but I don't think I've
tried that one.

In case the problem of reproducing is a matter of the software
accessing owserver, the software I'm using is here:

http://voksenlia.net/met/src/owfslog.c

It's not fully release quality, but anyone is free to download and try
it.  It reads a configuration file describing which owfs files to log
and creates a thread or process (selectable) for each file which goes
into a loop reading the file at a given interval.  An optional
queueing mechanism can be used to prevent simultanious requests to a
single owserver (which used to cause a problem).  It was written to
replace owwnogui which I had been using previously.

To be gentle on owserver I use the -q option (queueing using POSIX
calls).

Type owfslog -h to get a description of the configuration file format.

Type owfslog -x (or any invalid switch) to get a list of command line
options.

A quick start might be to make configuration file x.conf:

average(localhost:3000|1F.A1B104000000/aux/10.7F1914000800/temperature, %.3f, 3)

and run "owfslog -i 20 -t -q -c x.conf" which will read the file every
three seconds and log the average every 20 seconds.  Add a few more
entries to the configuration file (so several hub ports get used) and
run for an hour or so.  In my setups p26 will fail on most or all
files by that time.
