Yup, this is most likely due to how Huawei are using different "Linux" and "Windows" modes. Different mode switch commands will make the Huawei modems appear differently, and even use different device IDs. The problem is that there are no Windows drivers for the Linux mode. Not much we can do about that. We cannot fix Windows....
Linux can however support both Windows and Linux modes, so if you often reboot from Linux to WIndows without unplugging the USB modem then it might make sense to always run the modem in "Windows" mode. Try putting something like this in /etc/usb_modeswitch.d/12d1\:1505 [code] TargetVendor= 0x12d1 TargetProductList="140b,1506,150f,150a" ## Linux Default: #MessageContent="55534243123456780000000000000011062000000100000000000000000000" ## Windows mode MessageContent="55534243000000000000000000000011060000000100000000000000000000" [/code] -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1077118 Title: Connecting prevents Huawei E398 4G-modem to work rebooted into Windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/1077118/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
