I confirm this bug. In 13.04 i386 the DNA (ISP) 4g modem Sierra Air: lsusb: Bus 006 Device 003: ID 1199:68a3 Sierra Wireless, Inc. MC8700 Modem
did not work out of the box but following these instructions funcioned just fine: http://forum.ubuntu-fi.org/index.php?topic=42920.0 The forum is in finnish but basically required to create the file /lib/udev/rules.d/81-mm-sierra.rules with the contents: SUBSYSTEM=="tty", ATTRS{idVendor}=="1199", ATTRS{idProduct}=="68a3", ENV{ID_MM_CANDIDATE}="0" SUBSYSTEM=="net", ATTRS{idVendor}=="1199", ATTRS{idProduct}=="68a3", ENV{DEVTYPE}="net" After the std upgrade to 13.10... the Sierra is no longer recognized as wwan0 and I for one have not been able to figure out yet what to do to fix this. I would rate this severe, a confirmed bug and it affects at least all DNS clients with this modem. Following these instructions: http://mycusthelp.net/SIERRAWIRELESS/_cs/AnswerDetail.aspx?aid=44 to install sierra's own drivers did not help! If needed, I am willing n able to supply further info for debugging and fixing this issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1219256 Title: usbnet changes in 3.10 stop use of sierra_net devices To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1219256/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
