Thank you, Danillo. This was the only thing that worked for me on Ubuntu 14.04 and Mint.
Yes, the bug is still happening in saucy and trusty. Haven't tested utopic yet but I bet it's the same there because every bug I have found on this topic has been marked as allegedly resolved or expired despite people commenting that it's still broken. This isn't just Huawei devices, it's ANY modem that spawns multiple /dev/ttyUSB interfaces - Sierra devices, for instance. Why can't at least an option be added to manually choose the correct port? Fedora Network Manager apparently has that, as indicated by Huawei's installation manual, and it's a very simple solution. Either way, it's unacceptable that this bug exists for so long and is ignored, forcing people to resort to wvdial or to buy another modem.
