Hi!
> [...] will probably fix your problem
Thank you for being kind. As far as I can tell, the modem is working
correctly, I wrote to this list because I saw a
"usb_modeswitch: please report the device ID to the Linux USB developers!"
message and I thought that reporting was my duty :-). But now I have the doubt
that if the reporting must be done always, or only in some cases.
This is the last message and the prior ones:
Jul 23 19:19:53 laptop kernel: [63032.491639] sd 32:0:0:0: [sdc]
Attached SCSI removable disk
Jul 23 19:19:53 laptop usb_modeswitch: switched to 19d2:ffffffff on
002/045
Jul 23 19:19:54 laptop usb_modeswitch[9252]: usb_modeswitch: switched
to 19d2:0117 on 2/46
Jul 23 19:19:55 laptop usb_modeswitch[9252]: usb_modeswitch: add
device ID 19d2:0117 to driver option
Jul 23 19:19:55 laptop usb_modeswitch[9252]: usb_modeswitch: please
report the device ID to the Linux USB developers!
Maybe some text could be added to the last message to let the user know when
he should report the device ID to the Linux USB developers (always, or only in
some cases).
If the device 19d2:0117 is already supported by the option serial driver, as
you said, then it's possibly an effect of the bug that you talked about in the
text:
"What we see here is a device not being stable on the usb bus and the
same has been reported for Ubuntu 14.04, multiple switching due to the
device being reset"
and then other people may write in this list while this bug is not solved.

Yes, yesterday I plugged in and out the device many times when I had to do
some tests, you are clever :-). I looked for that "please report the device
ID to the Linux USB developers" text in the other /var/log/syslog* files, and
it isn't there, that message only was in the log of yesterday.
Many thanks for all!
