I got message content from usb sniffer's log message.There are lots of messages in that , I tried above one and it works when I do reboot and some times when I plug out and plug in modem. Is it hardware issue or the message I am trying ? Please help me , how to choose correct message from log message ..

Thanks and Regards

Can you post the complete sniffing log to "pastebin.com"? I'd like to have a look.

From your log, the command you tried is the obvious choice. It may need a certain combination with other commands though.

Just for confirmation: you sniffed only on the original ID (05c6:2001) ? You started the sniffing log immediately before plugging in ?
I'm asking because I missed the device initialization phase in your log ...

But in between - just for fun - try this command:

...
MessageContent="5553424312345678000000000000061b000000020000000000000000000000"

I'm afraid this log is similar to the first one.

Did you install the filter on "Vid_05c6 & Pid_2001" ?
The Windows driver is installed ?
The log is deleted ?

If you plug in after all these steps, your log should start at "0 ms" rather than "2247827 ms" as in your posting. There should be something in the log like URB_FUNCTION_SELECT_CONFIGURATION after a short while.

You can stop logging when pressing "Refresh" does not show anymore size changes of the log.

Hey it was my mistake , I clicked on pause log in between I guess..
Now I have collected full log ..but log file is too huge (around 6.5 MB),so I couldn't put it in pastebin so uploaded it on following location:
http://www.teradepot.com/q9zogis4qili/m ... n.log.html
Please go through it .

Hmm, there are several things about the log that are unusual.

First: sorry about being persistent, but - are you sure the Windows driver on the device was installed before the sniffing?
There is so much data traffic going on which usually does not happen when the driver is just doing the switch.

Second: the moment when the device is gone - switching completed - is around 70000 milliseconds. That's 70 seconds after plugging. Can that be right ??
