I believe you misread what the rules in the blogpost are doing :) I think the rules try to force the device into QMI mode, instead of the MBIM mode that would be picked up by default. This was a better choice for the Dell modem at that time because there wasn't support for running QMI commands over MBIM, and the Dell modem really required the FCC Auth command; but that is no longer the case, as MM already handles QMI over MBIM automatically as well as the FCC auth command for the Dell device. Anyway, in your case it seems the rules didn't work as expected because you're still in MBIM mode, which is the one I would anyway suggest. I believe you can remove all the udev rules, as the kernel (or usb_modeswitch, it depends) should choose the MBIM configuration as preferred automatically. That said, could you gather MM and mbim-proxy debug logs? I'd like to check whether the issue is exactly the same one: $> sudo systemctl stop ModemManager $> sudo killall -9 mbim-proxy $> sudo /usr/libexec/mbim-proxy --verbose > /tmp/mbim-proxy.log 2>&1 & $> sudo /usr/sbin/ModemManager --debug > /tmp/mm.log 2>&1 & (and retry reproducing the issue) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to modemmanager in Ubuntu. https://bugs.launchpad.net/bugs/1326954 Title: Sierra Wireless EM7305 (Fujitsu Lifebook S904) does not work after suspend/hibernate Status in ModemManager: Unknown Status in libmbim package in Ubuntu: Confirmed Status in modemmanager package in Ubuntu: Invalid Bug description: Ubuntu 14.04, x86_64, ModemManager-1.0.0-2ubuntu1 Card: Sierra Wireless EM7305 (PCI Express M.2 form factor) Expected: Sierra plugin is used Happens: Generic plugin is used instead After cold start the card seems to work almost fine, but does not come back after suspend or hibernate.
