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:

1. My config file "12d1:14d1" is in the /usr/share/usb_modeswitch directory as part of the compressed file configpack.tar.gz

2. I have modified the /lib/udev/ruled.d/40-usb_modeswitch.rules with the following line

# Vodafone (Huawei) K3770
ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="14d1", RUN+="usb_modeswitch '%b/%k'"

3. I have enabled logging on both udev.conf and /etc/usb_modeswitch.conf. This is what the logfile says for /var/log/usb_modeswitch_1-7:1.0 :

Thanks.

There is a little bug in a Debian patch for usb_modeswitch (version 1.1.7).

I suggest that you use the current source version from this site (1.1.8) with the current data package (20110619) which includes the K3770. It's easy to install; if you should need instructions, see the main doc page.

[SimonJ]

uninstalled version 1.1.7
compiled 1.1.8

Everything works! Thanks.

Just a note : 12d1:14d1config file wasn't yet included in the /usr/share/usb_modeswitch/ directory.

I also still needed to modify the /lib/udev/rules.d/40-usb_modeswitch.rules file

Regards

[Josh]

Did you install the data package as well?

As I said, the current version is 20110619.

[SimonJ]

Yes, downloaded the usb-modeswitch-data-20110619 and did a:

sudo make install

after uninstalling the original "usb-modeswitch-data" via Synaptic


If you want the 12d1:14d1 file I can email

thanks

[Josh]

Turns out you are right. Somehow this device has escaped.

I know I have prepared it for inclusion ... Oh well ...

Thanks for the notice.
