0b3c:f00c not recognized

[Luiz Angelo Daros de Luca]

I'm trying to use a Olivetti mobile modem in Ubuntu 14.04.
My system is fully updated but modem is simply not recognized.
It seems that version 2.2.0 fixes this. However, it is not available for 14.04.

Well, then upgrade your system to a version where your dongle is supported, Ubuntu 14.10 or 15.04 supports it through usb_modeswitch 2.2.0 together with the 2014-05-29 datapackage.

Yes, it works on new systems. However, isn't this a bug for a LTS release?
I'm not willing to upgrade the whole system for a single feature.

Btw, I installed the package from new Ubuntu version on 14.04 without problem and it solved my problem. Would it be possible to backport 2.2.x to 14.04?

usb-modeswitch 2.2.0 and newer versions doesn't work (regression) with lots of 3G modems - I've tested on several devices, like Vodafone (Huawei) K4510 and Huawei E303 - it seems udev or upstart simply doesn't run usb_modeswitch command, because I don't see any activity in /var/log/syslog after installing new usb-modeswitch 2.2.0+repack0-2 from ppa:mariusko/network-manager-backports (the same problems also with 2.2.3 version from Ubuntu 15.10 "Wily") :(, see bug #1407429

The latest upstream version of usb-modeswitch is 2.2.5, this version is packaged in Debian (unstable and testing) since July 2015, maybe this release doesn't have regressions with Huawei 3G/4G modems?

http://draisberghof.de/usb_modeswitch/ChangeLog

Version 2.2.5, 2015/07/16
    Fixed bug in configuration check, possibly leading to segfault (thanks,
    Leonid Lisovskiy); fixed Pantech commandline parameter evaluation (was
    not working at all); added driver unbind step via sysfs in wrapper,
    getting rid of the USB subsystem complaint "interface 0 claimed by
    usb-storage while 'usb_modeswitch' <does this and that>"
Version 2.2.4, 2015/07/14
    Fixed buggy check of USB configuration selection (possibly leading
    to segfault), tested with Alcatel X602D; removed call to 'libusb_strerror'
    from libusb initialization - not available in earlier libusb1 versions

Status changed to 'Confirmed' because the bug affects multiple users.
