I had this same problem with a Huawei E160E. I kept getting the error.. -108, input/output errors etc.
Looks like it works better now. I updated the firmware from my operator's site (Elisa Finland) (http://www.elisa.fi/asiakaspalvelu/499 /lataa-tiedostoja/). It worked ok in 10.x but it seems that in 11.x and up it very rarely worked. Kept on freezing for 10s etc. Now it works like before, meaning that after booting I have to disconnect the modem a few times, throw it against the wall, curse out loud.. and then it suddenly connects :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/772577 Title: Kernel in Natty disconnects Huawei E160G, ModemManager can't use it To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/772577/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
