I got it working after days of painful research
So the solution.
You have to trick linux into thinking it is a different modem, this involves installing usb_modeswitch and editing 3 files
The first file
sudo gedit /etc/usb_modeswitch.conf
add the following lines
DefaultVendor= 0x12d1
DefaultProduct=0x14d1
TargetVendor= 0x12d1
TargetProduct= 0x1c05
CheckSuccess=20
MessageContent="5553424312345678000000000000001106 0000000000000000000000000000"


The second file you will need to create
sudo gedit /etc/usb_modeswitch.d/12d1:14d1

Then add the following lines - yes almost the same as above
################################################## ######
# Huawei K3770

DefaultVendor= 0x12d1
DefaultProduct=0x14d1

TargetVendor= 0x12d1
TargetProduct= 0x1c05
CheckSuccess=20
MessageContent="5553424312345678000000000000001106 0000000000000000000000000000"

And finally the last file
sudo gedit /lib/udev/rules.d/40-usb_modeswitch.rules
Add the line


# Huawei Ek3770
ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="14d1", RUN+="usb_modeswitch '%b/%k'"

I rebooted after this and it works.
I did notice that if you startup with the modem it sometimes does not find it, just pull it out and put it back in.
It works with network manager

έγραψε:I have Ubuntu 11.04, I can manually switch my Huawei K3770 modem with the command:

sudo usb_modeswitch -v 0x12d1 -p 0x14d1 -c /home/USER/12d1:14d1

Then I need to do the command:

sudo modprobe usbserial vendor=0x12d1 product=0x14c9

And the modem works fine. I would like it to work automatically when I plug in the modem. I have followed various Forum posts and this is what I have done:
