I found !!!!!!!!!!!!!!!!!!!!!!!!!
The problem came from modem-manager lauched by dbus.
In order to desactivate I had to remove
/usr/share/dbus-1/system-services/org.freedesktop.ModemManager.service
The following trace on /var/log/messages put me on the rails:
Jun 13 14:32:24 f8arr2-station modem-manager[721]: <info> (ttyUSB0)
closing serial port...
Jun 13 14:32:24 f8arr2-station modem-manager[721]: <info> (ttyUSB0)
