Aug 16 22:09:47 ubuntu modem-manager: (Huawei): (ttyUSB0) deferring support check Aug 16 22:09:50 ubuntu modem-manager: (ttyUSB0): re-checking support... Aug 16 22:09:50 ubuntu modem-manager: (Huawei): (ttyUSB0) deferring support check I can see ttyUSB port only if I give: sudo killall modem-manager -- Huawei USB modem intermittently not detected: loop of "deferring support check" https://bugs.launchpad.net/bugs/501006 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
