Sorry for the delayed answer, but I'm very very glad to inform you that
the modem worked after the last configuration that you sent to me:
# Olivetti Olicard 500
The only thing that I need to do was remove the PPP that it was already
installed for the other modem that I was using before and then after
plug the Olicard 500 the Ubuntu asked me to create a new PPP and then
after create it everything works fine.
I'm sending attached to you the syslog file and also usb_modeswitch_1-13.
Thanks a lot, for you help.
My kind regards,
