Hi,
I'm playing with owfs, a DS9490 USB to 1wire adapter and a 18B20
temperature sensor for the first time (owfs-2.8p3 and tried 2.7p38 also
under Ubuntu 10.04 and a different machine with Ubuntu 9.10).
I grabbed a 1 meter long, 4 wire phone cable and operate the sensor in
parasite power mode (Vdd connected to GND)
Everything works fine with owfs, but suddenly the connection breaks and
reconnect attempts of owfs fails with the message above.
Logfile from 2.8p3 Ubuntu 10.04 attached.
What is driving me nuts is the fact that the disconnect may happen
between a test if the sensor file exist and the query to the file itself.
if [ -e $root/$sensor/temperature ]; then // fine
temp=$(cat $root/$sensor/temperature) // disconnected
return 1
fi
If I kill the owfs process and restart it, everything is fine for some
polls (sometimes only 1 sensor reread, sometimes 5-6 times).
To exclude a hardware problem, I just moved the setup to a Windows XP
machine and tested it with the Dallas demonstration application -
everything works fine.
Any help is very appreciated!
Bernd
