USB_ModeSwitch

Need help to run / configure / install MediaTek Wimax Usb card in Ubuntu 10.4.
All helping answers are warmly welcome.

Let's start with running "lsusb". If you can identify your device from the compact listing, get the details with
"lsusb -v-d <your:id>".

O.K., fine.

Basically there are two ways possible:

You are able to switch with an often-used command for ejecting the "pseudo CDROM"; then you are good to go
If number 1 does not work, you have to spy on the Windows driver and what it is doing to the device. There are links and examples on the main doc page, paragraph "Contribute".

But first, let's try this (always as superuser):

usb_modeswitch -I -v 0e8d -p 7109 -M "5553424312345679000000000000061b000000020000000000000000000000"

Thank you Josh now the results are as superuser.

Please Tell me next step. I also got the sniffUSB TXT file but it is to long to be in post so if u want that i can attach the file with your email.

Posted: **05 Dec 2010, 13:07**

So the "eject" command did not do anything. Well, now we know.

Yes, you can send the sniffing log with e-mail, but please compress it first (with zip or gzip).

Posted: **05 Dec 2010, 16:33**

O.K., I received your log file. Unfortunately, the passage that you logged is not useful. It is important that you install the sniffing filter on the correct device in Windows. And you have to start logging before you plug in.

- Make sure Windows drivers are installed.
- Check the box "List Devices Not Present".
- Look for "Vid_0e8d" and "Pid_7109" in the device list.
- It probably has a name with "Mass Storage" - or no name at all.
- Remove any other filters in the list.
- "Install Filter" on this device.
- Make log empty ("Delete Log")).
- Start logging ("Resume Log").
- Plug in.
- Press "Refresh" from time to time.
- The log will most likely stop growing.
- Then finish the logging ("Pause ..." and "Close ...").

Posted: **05 Dec 2010, 20:49**

Thank you for correction. Now i am again sending you the log file of device = 0e8d:7109.

Josh i let you one thing when first time i see the result of lsusb of device it shows device ID= 0e8d:7118 then after it changed into (0e8d:7109) maybe i use some command like modeprobe or some else.

Any how for your kind review i am sending both (0e8d:7109) and (0e8d:7118) usb snoop log files.

I am very mush interested in learning of this process so be with me.

Waiting for your answer.

Posted: **05 Dec 2010, 22:11**

I think I could spot the right sequence.

Principally, the device after switching is not interesting, what you can sniff there is just the normal modem initialization traffic.

But your first log for 0e8d:7109 contains the moment of switching; see the time mark [38310082 ms]. There the Windows USB system is seeing a IRP_MN_SURPRISE_REMOVAL.
This is where your first device (0e8d:7109) is going away. It is not much different than being unplugged.

Now, obviously the commands immediately before that moments are suspicious. And what we find is a sequence that is known from BandLuxe devices.

See "[38310045 ms] >>> URB 138 going down >>>"
and "[38310046 ms] >>> URB 140 going down >>>".

Look at the messages: you known the one in URB 140 because you already tried that. It's the "eject" command again.
But there is annother command preceding it; in URB 138 is a message that says "06 1e" where the eject command says "06 1b". This command enables the following eject.

You can read about storage commands here:
http://www.usb.org/developers/devclass_ ... -ufi10.pdf

Coming back to your device, you can test the following configuration. Put it in a file named "0e8d:7109" into the folder "/etc/usb_modeswitch.d":

Code: Select all

It seems that eject command works but cannot get it back to 0e8d:7118 to initialize the modem.
Looking forward for your reply on this issue now.

Posted: **06 Dec 2010, 08:56**

Hmm, but there seems to be only the first message sent. You should have two messages and two responses.

Are you running an older version of usb_modeswitch ?
The feature to send more than one command message was added in 1.1.2. If you have to upgrade anyway I'd recommend the latest version 1.1.5; it's already available as a Debian package:

http://packages.debian.org/experimental/usb-modeswitch

And the data package:

http://packages.debian.org/experimental ... witch-data

well now the both things are working what is the next step to scan modem and to connect it to the Internet.

Posted: **06 Dec 2010, 12:37**

That's much better!

There is only one more thing to do:

You need a line for your device in "/lib/udev/rules.d/40-usb_modeswitch.rules". Have a look at the other lines, it is really easy to see what has to be done. The line must contain the "7109" product ID.

Once you completed this everything should work automatically, including adding the driver to the modem.

Everything looks really good.

Forget about the errors in the output, they are expected because the device is gone already which means the switch succeeded.

With a simple "dmesg" command you can check if the driver has bound to the modem. Look for messages containing "ttyUSB0" or similar. If you see them after switching, you are all set.
