Ok I found new udev rules for my modem:
ACTION!="add|change", GOTO="mbim_to_qmi_rules_end"
SUBSYSTEM!="usb|drivers", GOTO="mbim_to_qmi_rules_end"
# load qmi_wwan module
SUBSYSTEM=="usb", \
ATTR{idVendor}=="413c", ATTR{idProduct}=="81a31", \
RUN+="/sbin/modprobe -b qmi_wwan"
# force Dell WWAN 5809e to configuration #1
SUBSYSTEM=="usb", \
ATTR{idVendor}=="413c", ATTR{idProduct}=="81a3", \
ATTR{bConfigurationValue}="1"
# add the new id in the qmi_wwan driver
SUBSYSTEM=="drivers", \
ENV{DEVPATH}=="/bus/usb/drivers/qmi_wwan", \
ATTR{new_id}="413c 81a3"
# load qcserial module
SUBSYSTEM=="usb", \
ATTR{idVendor}=="413c", ATTR{idProduct}=="81b1", \
RUN+="/sbin/modprobe -b qcserial"
# add the new id in the qcserial driver
SUBSYSTEM=="drivers", \
ENV{DEVPATH}=="/bus/usb-serial/drivers/qcserial", \
ATTR{new_id}="413c 81a3"
LABEL="mbim_to_qmi_rules_end"
Now I have both, ttyUSB* and /dev/cdc-wdm0, but modem still won't register
to network.
