ok............

i managed to reproduce this 3 times... and i think i found when (but not how) the switch or modem activation happens

i restore xp to a month ago... to plug the phone as it was the first time... so what happens here is that windows only detect a usb storage cd rom...

so i follow and clicked on "3G connect via the phone"... it installs dial up and some drivers and it automatically unplugs phone...

in that moment i check in linux dmesg and i get modem...

so i reconnect phone in windows and i get the 4 devices i posted before... but i found this... the usb mass storage it mounts the first time is not the usb mass storage it mounts the second time...

i imagine that i was sniffing the wrong usb mass storage...
as i found this reproduce it 3 times with same results... so i sniffed on the FIRST usb mass storage that appears...

its quite big cause it has the install of the dial up program but i didnt wanted to erase anything... it is like reading chinesse for me (you are aware that im not a developer right?)

http://www.gigasize.com/get.php?d=so0yvr9zslf

hope this helps... (still frustrated and going back to windows tho)

[Josh]

Now you're talking

The "lsusb" shows that the phone does indeed switch ... but it keeps the USB ID. You can see (in fact you did) that the interfaces are changing internally.

And your log has an interesting ending. The end is the only relevant part because that's where the old "CD ROM" is gone. The switch must happen immediately before that.

There is a suspicious command that you should try:

Code: Select all

usb_modeswitch -v 0x12d1 -p 0x101e -C 0xff -M "55534243123456780600000080000601000000000000000000000000000000" 

(in one line, as usual)

The "-C" option allows usb_modeswitch to decide if the device was switched or not. If you look at your both "lsusb" outputs, you can see that in "modem unusable" state, the first "bInterfaceClass" says "8". In "modem usable" state it says "255"(or 0xff in hexadecimal). That is the "TargetClass", and that is the way to distinguish which state the device is in.

The easiest way to test if the switch was successful is to run the same usb_modeswitch command again and see if it says "found device in target mode or class". Of course, "dmesg" should also have something to say.

THANK YOU SO MUCH!!!!!!!!!!!!!!!!!!!

just one more thing... can you help me to add this as an udev rule... so it does automatically... and to add this to some script to modprobe option when booting???

again... thank you soooooooooo much!!!!!!!!!!

ill post this everywhere!!!!!!!!!!!!!!

[Josh]

If you want your name in the usb_modeswitch.conf file (as contributor), mail or PM it to me.

I will do a new data release around noon (local, GMT+1) where your device is added to rules and configuration. You need the newest usb_modeswitch version (1.1.0) though; Debian provides it in "sid" if you don't have it already. With this, everything - including driver loading - will work automatically.

[pilchat]

Dear Josh,

I have almost the same problem with my Huawei V725 (aka Vodafone 725, it's a mobile phone).

I used to switch it in my Ubuntu 9.04 using the following script:

--------------------------------------------------------------
#!/bin/bash
usb_modeswitch -v 12d1 -p 1009 -d 1

sleep 20

usb_modeswitch -v 12d1 -p 1009 -H 1

sleep 20

modprobe usbserial

lsstring=$(ls /dev/ttyUSB*)

if [ "$lsstring" != '' ]
then
wvdial -C /etc/wvdial.conf.3.cell
fi

exit 0
--------------------------------------------------------------

It was usb-modeswitch 1.0.2-1, and everything worked fairly well.

Now I'm running Ubuntu Lucyd and usb-modeswitch 1.1.0-2. If I try just the first usb_modeswitch call, my phone seems to be detached, but soon after it is re-attached exactly the same way as the first time:

--------------------------------------------------------------

Moreover, "lsusb -v" keeps saying that the device is "Mass storage". I also tried some of the commands I found in the previous posts, without success.

I am not a master of usb-modeswitch, so I beg you to help me. I don't want to switch to windows everytime I need to connect to the internet using my phone as a modem.

[Josh]

The CDROM errors you are seeing are caused by changes in the kernel; the usb-storage driver adheres a bit stricter to the specification now, exposing quirks in the device firmware. But usually these errors have no impact on the switching process.

Did you ever try the newer Huawei switching method described in the previous posts of this topic ?

Like this (one line, of course):

Code: Select all

usb_modeswitch -I -v 0x12d1 -p 0x1009 -M "55534243123456780600000080000601000000000000000000000000000000"

Thank you for your quick reply. Let's sort it out.

When I plug my phone I get these messages:

I don't find any difference with respect to the first plug....

Any suggestion?

[Josh]

Hmm, maybe the code from the other Huawei phone works ? Try this behind the -M parameter:

Code: Select all

"55534243123456780600000080010a11060000000000000000000000000000"

Or this from the latest Huawei sticks:

Code: Select all

"55534243123456780000000000000011062000000100000000000000000000" 

After each attempt, check if the USB ID has changed with "lsusb".

[pilchat]

Nope, it doesn't change. It's stuck at:

"Bus 002 Device 004: ID 12d1:1009 Huawei Technologies Co., Ltd. U120"

Any other idea?

[Josh]

No other idea except going through the whole sniffing process to see what the Windows driver is doing.

[pilchat]

Sorry, but I am not a windows user. What does it mean?

[Josh]

See the main documentation page, paragraph "Contribute".

[pilchat]

Thanks! I used Mark's guideline and I sent you an e-mail with the log (it's a long file).

Let me know if you don't receive my email.

Thanks!

[Josh]

I got your mail.

Some remarks about that:
It would have been more polite to ask before sending such a big file. But even if sending it without asking for permission, the least you could do is to compress the files with ZIP or GZIP or whatever. That reduces the file size of a large text file to 10% of the original.
Also, BMP is the image format taking the most space of all possible. Consider using PNG or GIF for screenshots. Indexing your picture and saving it as PNG results in a file of 20 kB. Your BMP has 1800 kB.

My bandwith and volume is limited.

Now to the log file:
You managed to capture the moment of switching which is all that counts. Look at [292 ms], that is a control transfer very close to the moment where the device is "removed" at [3448 ms].

The control transfer is the old Huawei mode-switching command issued with the -H parameter, just what you did all the time. We know that for sure now. There must be other reasons why things are not working right.

The next things to check for is the timing and the kernel version. Regarding the latter, there are some kernels around 2.6.31 which make Huawei devices reset because of that "sense error" you are getting. If you have a kernel of that series, try to update, at least above 2.6.31.5, better to a 2.6.32 version.

If that does not help or apply then we will look at the timing more closely.
