I did not get what you say, so I am trying to connect by wvdial.
And I connected for 4 seconds! =))))))
But then it automagically disconnected...
Here is my /etc/wvdial.conf
Code: Select all
[Dialer Defaults]
Phone = #777
Username = login
Password = password
New PPPD = yes
Modem = /dev/ttyUSB0
Baud = 3686400
and here is output

And plus one problem: after disconnection you should restart computer because modem no more initializes...

You mean disconnection of the device? Or disconnection from the call?
The strange lines you see with lots of }}}} are produced by the pppd program, trying to negotiate a network connection. You really should let gnome-ppp or a similar program do the job, now that you know it works.
Just make sure it uses "ttyUSB0" as the modem device.

I mean device.
If you connect and then disconnect even in GNOME-PPP you can not connect again because system does not see modem.
If you will try to Detect it with GNOME-PPP it shows

And one more.
I finally get connected with GNOME-PPP and surf in Opera, BUT FireFox didn't work at the same time! How is this possible? =)

It has to be a setting in Firefox; that's logical.
Look for "Proxy Settings" or similar and see if it is set to "No Proxy". That is the only issue I can think of ...
Do you have other browsers?
You can also use the "ping" command to test if the connection and the name resolution is good ("ping
www.heise.de", stop with ctrl-c).

Correct. No problem with FF now.
But what I need to do to disconnect modem?
After pushing Disconnect I can not connect again =)

First, we need to find out if something is happening to the modem on the USB level. You know now how it looks if the device is switched alright - you see "ttyUSB0" if you call "dmesg".
Now, what does "dmesg" show after you connected and disconnected again?

So the modem is still there. It must be some other cause. I'm afraid I have no idea ...

Now I've capture using the 0xfffd 0xff6 device which are actually the storage device and after they gets switched to modem mode which 0xfff1
Any clues ?

Yes, that's the right one. And look at the second last bulk transfer "going down" (starting at line 639). That's the same message as khurtsiya's.
So just try the same steps but with your slightly different IDs.

Hi there! I am back again
Just bought Asus Eee PC 901 and trying to use modem there.
Copied there my usb_modeswitch.conf and wvdial.conf.
When typing sudo usb_modeswithch it freezes here:
Code: Select all
Looking for default devices
Found default devices (1)
Accessing device 005 on bus 002 ...
Using endpoints 0x05 (out) and 0x84 (in) ...
Inquiring device details; driver will be detached ...
Looking for active driver ...
OK, driver found ("usb-storage")
OK, Driver "usb-storage" detached
and that is all...
Any ideas why on Acer Aspire works and on Eee PC not?
TIA
Michael

Are you able to stop the hang with <ctrl-c> ?
If not, can you use a second terminal at the same time and call "dmesg" right after the freeze?

I stopped it and this is what I've got:

The last line shows the problem:
Code: Select all
scsi 3:0:0:0: rejecting I/O to dead device
This may be a hardware problem (try annother port, try a powered hub) or a kernel problem of your distribution. If you can, try a plain vanilla (original, unpatched) kernel.
