I concur, modemmanager is far too aggressive. Please take a look at these bugs, too:
https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/686418 https://bugs.launchpad.net/ubuntu/+source/gobi-loader/+bug/621743 https://bugs.launchpad.net/ubuntu/+source/gobi-loader/+bug/647471 gobi-loader is often blamed, but modemmanager is the culprit trying to access the QDL device while the firmware load is still in progress und thus corrupting the upload. Blacklisting all USB QDL devices of the Gobi modem solves the problem by stopping modemmanager from accessing the corresponding devices. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/490194 Title: /sbin/modemmanager is too aggressive managing devices that aren't known to be modems -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
