The kernel oops is btw from ModemManager and not from usb_modeswitch. Make sure by checking the system log (after removing the faulty config in usb_modeswitch.conf) that usb_modeswitch switches the dongle from 12d1:14fe to 12d1:1506 at every insert. If it does, then assign the bug to NetworkManager which should handle the dongles direct ethernet interface (cdc_ncm, huawei_cdc_ncm, and cdc_wdm. see the log for those). It should not be handled by ModemManager which is for ppp dialup even though the dongle supports that mode.
