I seem to be experiencing something similar with 12.04 and a mifi 2352, no additional software installed:
it works sometimes, sometimes it does not that means, sometimes after plugging the device into the usb port 'dmesg' shows lines like "usb 2-1.1: GSM modem (1-port) converter now attached to ttyUSB0" and the modem is useable and sometimes (when plugging it in again) these lines do not show up and there is no modem accessible -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/885316 Title: Mobile broadband aspect of modem/storage device not showing up in NetworkManager -- Huawei E220, Novatel Wireless MiFi® 2352 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/885316/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
