k3770 Modem on Natty , How ?

[qDot]

Ok, The Vodacom K3770 modem from Vodacom.

I googled around, saw some references to modeswitch over here and I still do not understand.

Please help.

Modeswitch is already installed by default on Natty and if its not being picked up then the UDEV rules are not available for the modem - in other words, don't prick around and just a while for an update to come in to support the modem.

Use Sakis3G from http://www.sakis3g.org/

Best of luck!

Check out the USB_ModeSwitch forum, Josh is very helpful.

unplug the modem, open a new terminal window type:

sudo tail -f -s 1  /var/log/messages

Replug the modem, you should be able to determine where the modem gets mounted by looking at the output in the terminal window.

my output to tail:

I finally got it working, took me a lot of research but once I figured it out it was really easy. I have installed it now on 3 different machines and different versions of Ubuntu.

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

Thanks cre8tor

Mine now switches, but unfortunately never gets to the point of asking for the SIM pin.
lsusb shows up: Bus 001 Device 008: ID 12d1:14d1 Huawei Technologies Co., Ltd.

Pop-up has changed to:
"CD-Drive Connected" followed by
10.103.blah blah RC1 Successfully Unmounted

Which is similar to what the older ZTE modem I'm borrowing says (sans the "CD-Drive" bit) before it asks for the pin code.

2 reboots later, and the Huawei still just sits there with a double green led flash every 3 seconds or so.

Any ideas?

try
sudo modprobe usbserial vendor=0x12d1 product=0x1c05
