Before that happened always when i connected modem to USB port ethernet connection was applied automatically. Now after i plug modem to USB system recognize it as a CD/DVD device, file manger opens that CD root location, and there is no available connection in the Network Manager. And when i try :
usb_modeswitch
it says:
usb_modeswitch -v 12d1 -p 1f01 -W -J
Take all parameters from the command line
* usb_modeswitch: handle USB devices with multiple modes
* Version 2.2.5 (C) Josua Dietze 2015
* Based on libusb1/libusbx
! PLEASE REPORT NEW CONFIGURATIONS !

How can i fix this? P.S. Don't know if it is related but it happened in a short time after i was doing some changes related to create .ISO image with k3b and brasero.
