Hello

Thanks very much for so quick answers.

@Steinar No usually the lost device(s) don't re-appear after restarting owfs 
and owserver. But it may vary. I have done so much tries and couldn't catch 
any evidence of doing this or that solve the issue. Now I just wait and the 
lost device(s) come back by itself. But it's annoying.

@Jan, Ok I'll do as you suggest. I've just installed ow-shell because it was 
not installed on my system. (2.8p15 from Raspbian repo). I now have the 
commands owdir, owread etc..
I have launched a small script to monitor the 1wire bus. Usually my bus 
report 7 devices, this script will log the output of the commands "ls 
/mnt/1wire/uncached/" and "owdir /uncached" when there is no 7 devices. So 
we'll be able to see if there is any difference between those 2 commands. 
Thanks for giving this path to follow. Here is my script:

#!/bin/sh
# 23 Mai 2016 -- Script to check if any device disappear from 1wire bus

while :
do
  sleep 5  # check every 5 seconds
  HOW_MANY=`ls -ld /mnt/1wire/uncached/??.* | wc -l` # On my system this must 
return 7 when no problem
  # echo $HOW_MANY
  if [ $HOW_MANY -eq 7 ]; then
    :  # do nothing
  else    # log the output of "ls /mnt/1wire/uncached " and "owdir /uncached" 
(filter for devices directory only)
    echo "==========================================" >> /tmp/LogCheck1wire
    date >> /tmp/LogCheck1wire
    echo "======== ls /mnt/1wire/uncached ==========" >> /tmp/LogCheck1wire
    ls -ld /mnt/1wire/uncached/??.* >> /tmp/LogCheck1wire
    echo "=========== owdir /uncahed ===============" >> /tmp/LogCheck1wire
    owdir /uncached | grep 00 >> /tmp/LogCheck1wire    # On my system all 
1wire devices end with 00 so this lists 7 devices
    echo "==========================================" >> /tmp/LogCheck1wire
  fi
done

By the way here is my kernel info:
$ uname -a
Linux Box 3.18.11+ #781 PREEMPT Tue Apr 21 18:02:18 BST 2015 armv6l GNU/Linux

Best regards
