Hi, We have the HP EliteBook 820 G3 with the HP lt4120 Qualcomm® Snapdragon™ X5 LTE Mobile Broadband Module and it is also not being recognised in any flavour of Ubuntu 16.04.
After a clean setup, the lt4120 is recognized as a second ethernet card. We had the same issue on another HP laptop, ProBook 640 G2, and solved for Ubuntu 14.04.4 LTS creating a '99-XXX.rules' file on '/etc/udev/rules.d/' folder. (Attached in case is useful for someone) This solution doesn't work for the EliteBook 820 G3 and Ubuntu 16.04, neither Ubuntu 14.04: After adding the '99-XXX.rules' file now we can see the 'Mobile broadband enable' options under the Network Manager system bar, so the card is not recognized as ethernet. But it does nothing when selecting it: always appears as "Disabled Mobile Broadband". ** Attachment added: "Possible solution with 99-XXX.rules" https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1574582/+attachment/4683030/+files/99-XXX.rules -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1574582 Title: HP lt4120 Snapdragon X5 LTE USB modem not recognized by network- manager Status in network-manager package in Ubuntu: Confirmed Bug description: USB modem not recognized by network-manager.
