Using k3765 3G USB modem in Linux

In normal cdrom mode... usb_modeswitch.conf:

DefaultVendor=  0x12d1
DefaultProduct= 0x1520
MessageContent= "55534243000000000000000000000011060000000000000000000000000000"

execute:

usb_modeswitch -c /opt/etc/usb_modeswitch.conf
modprobe usbserial vendor=0x12d1 product=0x1465

Disable cdrom mode with:

AT^U2DIAG=0

Then I need only:

modprobe usbserial vendor=0x12d1 product=0x1001

to use it with smsd.
