That is okay. Thanks for the help, anyway.

Yes, that sounds sensible.

Thank you for the link, Visakh. The post is well written and clear. But
I have one doubt. He writes, "Using lsusb I found that the device has
three configurations." Then he goes on to use the command,

sudo usb_modeswitch -v 230d -p 0001 -u 3

to switch the device to modem mode. But, as you have seen, the lsusb
command in my case does not give any such details, like what should be
the number to follow -u in the command. Could this be because, as you
say, "The device may be so new that linux support may be just
appearing"?

I am attaching as a text file the output of the lsusb -vd 230d:0007
command just for your knowledge. I have not done any experiments as you
have suggested. I shall do that later and let you know the results. But
this output seems to say that here also it is mode 3, unless I am
mistaken.

Thanks and regards,
Sasi

[fsug-tvm] Re: Connecting Windows 7 to ubuntu

[Visakh]

Hi,

  Sorry for the late reply. 

  Default method for sharing between Win and Lin is using the smb protocol. 
Install Samba (linux implementation of smb) and any required samba admin 
application in linux. Also, enable the folder sharing option (from folder 
properties, sharing tab). In windows, enable sharing as well. Take care to 
use same workgroup name in both systems. Other than this, you will have to 
do the appropriate IP settings was well.

  Do write back if you need more help.

Gokul Das

[fsug-tvm] Re: Problem with Visiontek 3G modem

[Visakh]

Hi,

@ Sasi sir,

Software problems tend to be predictable and repeatable. This one 
sounds otherwise. So I can't say for sure I have a solution. But I did find 
a possible explanation and solution. The device may be so new that linux 
support may be just appearing (note that the USB vendor and device IDs are 
not recognised in the lsusb output). A solution to similar problem in a 3G 
dongle from the same vendor is given in the following blog:


http://amit-mendapara.blogspot.in/2010/11/amazing-bsnl-3g.html

The post has a detailed explanation of the solution (assuming that I am 
looking at the correct problem). Others also have suggested the same 
solution. The problem description is given by the 
usb-modeswitchtool site as:


More and more USB devices (especially high-speed WAN stuff, based on cell 
> phone chipsets containing that feature) have their MS Windows drivers 
> onboard; when plugged in for the first time they act like a flash storage 
> and start installing the driver from there. After installation (and on 
> every consecutive plugging) the driver switches the mode internally, the 
> storage device vanishes (in most cases), and a new device (like an USB 
> modem) shows up. Modem maker "Option" calls that feature "ZeroCD (TM)" 
> since it eliminates the need for shipping a separate driver carrier.
>
> In the beginning, nothing of this was documented in any form and there was 
> hardly any Linux support available.
> On the good side, most of the known devices do work in both modes with the 
> available Linux drivers like "usb-storage" or "option" (an optimized serial 
> driver for high-speed modems).
> That leaves only the problem of the mode switching from storage to modem 
> or whatever the thing is supposed to do. 
>
What I believe is the problem is that your USB dongle is getting mode 
switched correctly only in some instances - may be due to some other 
factor. Sir, you could do some experiments as suggested in the blog to 
determine if this is indeed the problem. If you need assistance with more 
analysis, please post the result of the following command (The result would 
be enlightening for me and others even otherwise):
*lsusb -vd 230d:0007*


@ Arun sir,

I believe that you modem is device 19d2:2003. Could you post the result 
from:

*lsusb -vd 19d2:2003
*

Gokul Das
