Comment 4 for bug 1334954

Please state which Ubuntu version, linux kernel version, and usb_modeswitch version you are using and also the content of the udev popup message.
The usb_modeswitch.conf file is for global configs and should not be used for individual device configuration, there should be a device config file named 12d1:14fe in the usb_modeswitch data package which you can find in /usr/share/usb_modeswitch/configPack.tar.gz

What you have entered in usb_modeswitch.conf is an incomplete device config (no switch method/switch message) so I doubt it has any effect, you should remove that.
