Whatever I try with the modem Huawei K3765 same result: It got switched to the modem mode, but ttyUSB nodes are not created. When same modem Huawei K3765 is inserted into Mint or Ubuntu it gor switched and recognized by Networkmanager. In all cases I have installed usb_modeswitch and ModemManager. So it seems something is not right on kernel.

I have Vodaphone stick K3765 and it got switched by the usb_modeswitch from usb_modeswitch: switch device 12d1:1520 on 001/002 to usb_modeswitch: switched to 12d1:1465 on 001/003 but the no further steps are executed and no serialUSB devices created.
