Hi
can visit

http://www.draisberghof.de/usb_modeswitch/

check the listing in the device_reference.text

update the usb_modeswitch.d folder. also check the usb_modeswitch rules

as detailed Natty,known bugs,and fixes Post #30

Start from .If the device is not switching:

the companies continually issue new variants;

I see from this

http://article.gmane.org/gmane.linux.kernel/1179341

Andrew Bird (4):
USB: option driver: add PID for Vodafone-Huawei K3770
USB: option driver: add PID for Vodafone-Huawei K3771
USB: option driver: add PID for Vodafone-Huawei K4510
USB: option driver: add PID for Vodafone-Huawei K4511

that it will be written into the 3.1 kernel; but that is months (2-4) away

seems the ID when switched should be

12d1:14ca Huawei Technologies Co., Ltd.

this is from here

http://www.draisberghof.de/usb_modes...603db55b05bce8

all I can suggest is installing the latest usb_modeswitch; and its data package from here

http://packages.debian.org/sid/usb-modeswitch-data data package

and here

http://packages.debian.org/sid/usb-modeswitch for the programme

.......choose the appropriate version for your processor at the bottom of the page

so this device has been investigated recently

+# Vodafone (Huawei) K3771

+ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="14c4", RUN+="usb_modeswitch '%b/%k'"

this is from here

https://github.com/andrewbird/usb-mo...ebe422c43e4c70

so one could add this I think to an existing usb_modeswitch by

sudo gedit /etc/udev/rules.d/K3771.rules

you will be asked for your sudo password; enter it; hit the ENTER key;

that will open up gedit, a text editor, and an empty file

if you copy and paste the above into it

ie

+# Vodafone (Huawei) K3771

+ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="14c4", RUN+="usb_modeswitch '%b/%k'"

and SAVE and CLOSE

if you reboot, we would hope the ID for the Huawei would now be

12d1:14ca

Thanks to everyone who posted in this thread. All the guides helped me, including the link to Git Hub.

I have written a guide on my website that goes through the process of adding a new device to usb_modeswitch that hopefully can be used for ANY new device (as long as you know the target product idea). The detailed guide can be accessed at https://sites.google.com/site/thealm...internetubuntu

A quick and dirty version (this does not go through WHY we are doing the steps, only what to do. If you want to understand the thought processes look to the guide on my site):

1. The ID of a device can be split into two parts; the first part (12d1) is the vendor code, and the second part (14c4) is the product code. We need to manually tell the system to switch over to the mobile broadband part (this is what the installer does automatically for Windows and Mac). To do this we run the following command:
   

   sudo gedit /lib/udev/rules.d/40-usb_modeswitch.rules

   Either add to the end of the file or do a search to find similar devices and add:
   

   # Vodafone (Huawei) K3771 (edit the following to your devices id)
   ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="14c4", RUN+="usb_modeswitch '%b/%k'

   "
2. The mobile broadband device has it's own product id that we must link to the installer product id. This is where it gets tricky; you need to figure out what this id is and at this stage I have no other advice other than to Google and pray. Luckily for me I know that my device id is 12d1:14ca. Now we need to create a custom usb_modeswitch rule.....
   
   Navigate to the directory /usr/share/usb_modeswitch/ by running the following command in a terminal:
   

   cd /usr/share/usb_modeswitch/

   If you perform an ls you will see that this directory contains a file called configPack.tar.gz. This file contains all the switching rules; we need to edit it to add our device. First back up the file through:
   

   sudo cp configPack.tar.gz configPack-ORIGINAL.tar.gz

   Now we will extract the scripts through running:
   

   sudo mkdir configPack/; sudo tar xzf configPack.tar.gz -C configPack/

   Run the command to open a text file for our new rule (replace the 12d1:14c4 part with the id of your device):
   

   sudo gedit configPack/12d1\:14c4

   This will open a completely blank document. Add the following text (remember to customise for your particular device!):

   Now we need to repack the rules and clean up our mess:
   

   cd configPack/; sudo tar -czf ../configPack.tar.gz *; cd ../; sudo rm -rf configPack/

   You can check the contents of the file by running the following command:
   

   sudo file-roller configPack.tar.gz

3. Now restart your machine and, fingers crossed, the system will now correctly detect your device!
