Any ideas?

That looks ok to me, now you need to use either normal Debian/Ubuntu config files to setup WAN access or user NetworkManager or some other GUI tool to do the same...

First thing seems to be to use usb-mode-switch to get it out of the Windows installation mode where it emulates mass storage / a CD-ROM drive ...

I miss the huawei_cdc_ncm module. Does not seem to be present in 3.10.

After digging for  a while what I understand stick got switched to modem mode

I have installed usb_modeswitch usb_modeswitch-data and modemanager

initial lsusb gives

Code:
Bus 001 Device 006: ID 12d1:1520 Huawei Technologies Co., Ltd. K3765 HSPA
after usb_modeswitch
Bus 001 Device 007: ID 12d1:1465 Huawei Technologies Co., Ltd. K3765 HSPA


But system does not know what to do with the device. From the syslog...

Mar  6 05:56:00 localhost NetworkManager[674]: <info>  [1488779760.7139] devices added (path: /sys/devices/soc.0/1c1a000.ehci0-controller/usb1/1-1/1-1:1.1/net/wwan0, iface: wwan0)
Mar  6 05:56:00 localhost NetworkManager[674]: <info>  [1488779760.7140] device added (path: /sys/devices/soc.0/1c1a000.ehci0-controller/usb1/1-1/1-1:1.1/net/wwan0, iface: wwan0): no ifupdown configuration found.
Mar  6 05:56:03 localhost ModemManager[637]: <info>  Couldn't find support for device at '/sys/devices/soc.0/1c1a000.ehci0-controller/usb1/1-1': not supported by any plugin

After reading https://wiki.debian.org/Modem/3G
I tried to
modprobe usbserial vendor=0x12d1 product=0x1465

but no ttyUSB* are created.

How I can check whether USB-modems are supported by the kernel?

hi, I edited your posts to include code blocks ... so that you can see what they look like;  anytime you want to list code or long lists, or logs,  or feedbacks  it is helpful for reading to place code blocks around  the list.  

The code block can be manually coded, or you can use the code icon on the full editor.

Your output looks ok to me, it created the wwan0 network interface. But you need also the ttyUSBxxx or ttyACMxxx serial ports to configure/control the modem. I read a bit about your stick and it seems there is a way via the 'option' kernel module to force the serial driver to recognize the PID/VID.

Other people seem to have had luck with adding UDEV rules like 

Code:
SUBSYSTEMS=="usb", ATTRS{modalias}=="usb:v12D1p1465*", KERNEL=="ttyUSB*", ATTRS{bInterfaceNumber}=="00", ATTRS{bInterfaceProtocol}=="ff", NAME="ttyUSB_utps_modem"

SUBSYSTEMS=="usb", ATTRS{modalias}=="usb:v12D1p1465*", KERNEL=="ttyUSB*", ATTRS{bInterfaceNumber}=="03", ATTRS{bInterfaceProtocol}=="ff", NAME="ttyUSB_utps_diag"

SUBSYSTEMS=="usb", ATTRS{modalias}=="usb:v12D1p1465*", KERNEL=="ttyUSB*", ATTRS{bInterfaceNumber}=="04", ATTRS{bInterfaceProtocol}=="ff", NAME="ttyUSB_utps_pcui"

I added these lines into something like (/lib/udev/rules.d/40-usb_modem...) do not remmeber right now. But still ttyUSB does not pop up.

How can i check whether
CONFIG_PPP
CONFIG_PPP_FILTER
CONFIG_PPP_ASYNC
CONFIG_USB_SERIAL
CONFIG_USB_SERIAL_GENERIC
CONFIG_USB_SERIAL_OPTION

options were compiled into the kernel?

Hi Dikov, you can check that in various ways, depending on how your system is configured, you can see if there is a current copy of you kernel config in /boot/ or if there is the special file /proc/config.gz . Also if you have the source for your kernel, you can just check with which options it was compiled in the repo:
