I am facing difficulty in installing my USB modem in Ubuntu 13.10. Contrary to what many have suggested,it does not get detected automatically, nor does setting a new connection help. USB Device is listed in lsusb, but not under network manager or Devices, it is detected as a CD-ROM, what I understood from the web was that usb-modeswitch can be used to switch it to a USB device. Even 'Enable Mobile Broadband' option is not shown in network manager.

What was interesting is when I start laptop with windows 7 and use the USB modem and after that restart with Ubuntu, both Enable Broadband and the mobile broadband connection can be seen. Sadly, internet connection could not be installed.

I tried using USB-modeswitch command as suggested somewhere, but it does not seem to work. Following is the message.

Take all parameters from the command line 


 * usb_modeswitch: handle USB devices with multiple modes
 * Version 2.0.1 (C) Josua Dietze 2013
 * Based on libusb1/libusbx
