Here is my temporary solution with udev rules file:
# Switch the device over from CD-ROM emulation mode to modem mode
ACTION=="add", SUBSYSTEM=="scsi_generic", ATTRS{idVendor}=="0930", ATTRS{idProduct}=="0d46", RUN+="/usr/bin/eject /dev/%k"
# Load option module when the modem mode of the device is detected
ACTION=="add", ENV{DEVTYPE}=="usb_device", ATTRS{idVendor}=="0930", ATTRS{idProduct}=="0d45", RUN+="/sbin/modprobe option"
# Set modem IDs as a new serial port device to option driver
ACTION=="add", SUBSYSTEM=="drivers", DEVPATH=="/bus/usb-serial/drivers/option*", RUN+="/bin/sh -c 'echo 0930 0d45 >/sys/%p/new_id'"
# Toshiba G450 HSDPA modem udev rules

# Switch the device over from CD-ROM emulation mode to modem mode
ACTION=="add", SUBSYSTEM=="scsi_generic", ATTRS{idVendor}=="0930", ATTRS{idProduct}=="0d46", RUN+="/usr/bin/eject /dev/%k"
# Load option module when the modem mode of the device is detected
ACTION=="add", ENV{DEVTYPE}=="usb_device", ATTRS{idVendor}=="0930", ATTRS{idProduct}=="0d45", RUN+="/sbin/modprobe option"
# Set modem IDs as a new serial port device to option driver
ACTION=="add", SUBSYSTEM=="drivers", DEVPATH=="/bus/usb-serial/drivers/option*", RUN+="/bin/sh -c 'echo 0930 0d45 >/sys/%p/new_id'"
