I have the same problem. It seems as if the usb-storage module constantly restarts the modem. Using rmmod to unload the usb-storage module (when the modem is active and the /dev/ttyUSB0 and /dev/ttyUSB1 devices are present) seems to help. This might have something to do with that the modem also emulates a CD drive which contains drivers for Windows. Also, If I unload the usb-storage module when the modem has been switched off by usb-storage, then the ttyUSB0 and ttyUSB1 devices will not be present and I'll be unable to connect to the internet using my 3G modem.
http://pastebin.ca/975812 This paste is from /var/log/messages when trying to connect to the Internet using the Huawei e220 HSDPA 3G modem with usb-storage loaded. http://pastebin.ca/975984 Here I unload the usb-storage module and can now successfully connect to the Internet. (Before unloading the module I also killed the NetworkManager processes because of this bug: https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/191889 ) http://pastebin.ca/975989 While I am connected I load the usb-storage module again (This also occurs when connecting a USB-disk), my connection dies and the modem begins to reboot again. Becuase of this I will not be able to use any usb-storage devices when I'm connected to the internet. -- Hardy Heron 8.04b https://bugs.launchpad.net/bugs/210444 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
