I think you can get help here ...

First it might help to read a bit more about the mode switching issue, to understand what is going on and how usb_modeswitch is working. I think you know the main documentation page by now, right?

The next step is trying to switch modes of your device manually with a custom config file or with the command line parameters.

If you have found a working configuration, make the switching automatic by adding the values to the right folders and files.

Note: please do not use the global configuration file "/etc/usb_modeswitch.conf" for device-specific configurations!
You can create a little text file with any name you like and then use it with "usb_modeswitch -c <yourconfigfile>".

- Remember to run every command with "sudo".
- Re-plug the device before each new attempt.
- Check with "dmesg" if there were any visible changes after running a test command.

I assume you have installed the data package too. There is a config file containing the same vendor ID which you could try to copy and adapt to your values: "230d:0001".

now finish my all configuration but i dont know what is right or what is wrong i search all configuration on Google or some linux site so i mix all configuration or i dont know which is work or which is unnecessary so please help me to short or right configuration
i can also connect thru networkmanager or when i am connected i also can use visiontek driver source which is located on usb net stick on /dev/sr1

help me i am waiting for your help......

[Josh]

As I said, start by trying to switch manually. Your config file looks O.K..

So plug in, then run:
$ sudo usb_modeswitch -W -I -c /etc/usb_modeswitch.d/230d:0007

Post the output.

[gaurav42]

yes
my usb 3g modem also work fine with above configuration with knetworkmanager mobile broadband,
but when network disconnected,
then i can not reconnect net.
i must plug out then plug in my usb net stick then i can re connect net.

so this is not proper way i think i will damage my usb port or usb 3g net stick if i always replug before connect .

after first disconnection i can not reconnect thru my modem it is hangup so please give me solution what should i do for solve this problem

[Josh]

Sorry, I have no idea what the problem might be with knetworkmanager. I only know some things about switching.

If I were in your place, I would test other connection tools to see if they show the same problem. If not, then knetworkmanager is responsible and you should report a bug there.

[gaurav42]

solved visiontek 3g

hi my problem solved

hi thanks to all for give me best support

today i solved all problem.

i update knetworkmanager to plazmoid-networkmanager with command

zypper install plasmoid-networkmanagement

& now i connect my visiontek usb net stick without any problem

i can use internet without any problem.

thanks again to all ...
