the recommend change should be applied to "usb_modeswitch.conf" ( if any) . try edit the /lib/udev/rules.d/40-usb_modeswitch.rules to disable the rule place a # at start of the line , example Quote: # Huawei E220, E230, E270, E870 # ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1003", RUN+="usb_modeswitch '%b/%k'" this should allow the use of modems which require switching. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/868034 Title: Huawei E220 can't connect on Ubuntu 11.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/868034/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
