This has already been fixed, as the patches for this are now included in the current released kernels for Ubuntu 12.04 and 12.10. You shouldn't have to do anything with the driver from Sierra Wireless. It should "just work" and be detected automatically when you plug in your usb modem device. If you have previously installed a separate driver (eg. from the Sierra Wireless website), then you will need to uninstall that to revert to the driver included in the kernel. If you run "modinfo sierra" and "modinfo sierra_net" from a Terminal window, you should see the following driver versions: $ modinfo sierra filename: /lib/modules/3.5.0-19-generic/kernel/drivers/usb/serial/sierra.ko license: GPL version: v.1.7.16 description: USB Driver for Sierra Wireless USB modems ... $ modinfo sierra_net filename: /lib/modules/3.5.0-19-generic/kernel/drivers/net/usb/sierra_net.ko license: GPL version: v.2.0 description: USB-to-WWAN Driver for Sierra Wireless modems ... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/933972 Title: Sierra Wireless 320U USB-to-WWAN modem is not detected (needs updated drivers from manufacturer website) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/933972/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
