USB_ModeSwitch

Posted: **17 Jul 2012, 16:07**

Hello,

I have an issue with a USB modem. It was working perfectly fine on Ubuntu 11.10. But has stopped working on 12.04. I posted at ubuntu forums. But I was suggested that I also post it on this issue forum. So I am hoping that someone here would help me. It is very much possible that there is a bug in ubuntu 12.04 and nothing related to usb_modeswitch.

I plugged the usb modem device in the computer. When I typed 'usb-devices' at the command prompt I obtained the following outputs on ubuntu 12.04 and 11.10:

Ubuntu 12.04:

Ubuntu 11.10:

I: If#= 3 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage

Then I compared the outputs of tail /var/log -f which is as follows:

So does anyone have any suggestion on this? Thanks!

Hmm, there seems indeed to be a problem with the mode switch.

Please enable usb_modeswitch's logging as described on the main doc page, paragraph "Troubleshooting".

Josh,

Thanks a lot for the reply. As suggested, I have enabled logging on Ubuntu 12.04 (on which it is not working). I have attached the log. Strangely, I found the log in the file, "/var/log/usb_modeswitch.log". The device name was not attached to the filename.

Let me know if you wish to see the log on Ubuntu 11.10 as well.

The switching sequence seems to be transmitted, but there is no mode switch. This is unusual.

Just for double checking, can you try to use the switching command manually? You need the file "12d1:1446" from the configuration collection, probably packed in /usr/share/usb_modeswitch.

Then run (as root or with sudo):

Code: Select all

# /usr/sbin/usb_modeswitch -I -W -s 10 -c "<path-to>/12d1:1446" -v 12d1 -p 1446

Dear Josh,

Thanks for the tip. Executing this command works wonderfully well

! This time it switched properly. I was able to connect to the net.

Only if I had messaged on this forum earlier, I could have saved so much time. Of course, it would be nice if this works automatically. Anyway, thanks a million!

Hmm, but this success is pointing to a possible problem in the Ubuntu package.

You should be able to replace the Ubuntu distribution package with either the latest Debian package or with an installation of the source package from this site. Both methods won't break anything, and you can always re-install Ubuntu's package.

Just uninstall your current package without checking for dependencies, as there may be a whole bunch of them.

The whole point of the package is to make things work automatically ...

Posted: **25 Jul 2012, 11:57**

Dear Josh,

Thanks for the response. I tried installing the debian package. But for some reason it failed. So for now I am content doing it manually. I will not complain if it does not work automatically.

But I certainly would like to raise a bug on this with Ubuntu. Any suggestions as to where I should do this?

Let me tell you about my observation on ubuntu 12.04. The folder, /usr/share/usb_modeswitch does not have any device file information. It has only one zipped file: configPack.tar.gz. I manually unzipped this file. And then I followed your command.

Thanks

Hi Josh,

I too have been facing this issue with my Ubuntu 12.04 installation - I have to switch the modem manually every time, but I just wrote a little two-line bash script for it.

I just thought the problem must have been solved by now...

Another niggling issue that I (and others too, I guess) have is having to replug the modem every time there is a disconnection, which again requires a manual switch. Now this wouldn't be a big problem if the computer weren't connected to my TV, making me get up and WALK to it.

Posted: **26 Jul 2012, 17:25**

The right place to file a bug against Ubuntu is
https://bugs.launchpad.net/ubuntu/

But I strongly recommend to try the source package first. Otherwise it is not clear if the problem results from the Ubuntu changes.

Posted: **27 Jul 2012, 09:27**

Dear Josh,

I tried to compile as you have suggested. But I am getting the following fatal error:

Code: Select all

$ sudo make install
gcc -o usb_modeswitch usb_modeswitch.c -Wall -l usb 
usb_modeswitch.c:58:17: fatal error: usb.h: No such file or directory
compilation terminated.
make: *** [usb_modeswitch] Error 1

So it looks like it is not able to locate the usb.h file. Does this have something to do with libusb? I installed libusb through synaptic package manager. Any suggestions here? Thanks!

Xlearner

Posted: **27 Jul 2012, 10:07**

Don't forget the "dev" package for libusb. It contains the header file "usb.h".

Posted: **27 Jul 2012, 11:51**

Josh,

After including the the dev package the code compiled without any problems. Now, the modem connects automatically as well

(after wating for a few mins since the device has been plugged in) ! Nothing better I can ask for

)!

Thanks

Hey this is good news! I will compile one myself tonight, and probably make it standard practice. I am not even sure if Ubuntu has been updating usb_modeswitch.

Josh, is having to replug the modem after disconnection expected behaviour on Linux, or is it an Ubuntu-only problem?

Posted: **27 Jul 2012, 18:40**

dune, this is not at all expected. I assume something is messing around with the device, and I suspect it's "modem-manager", the companion of "Network Manager", responsible for the "dirty work".

The problem is often that the Ubuntu/Gnome standard network software is trying to use advanced features of modems like signal strength display etc.

Unfortunately, the sheer multitude of modem models - and even firmware variants within the same family - makes it almost impossible to achieve this without device-specific information. So "modem-manager" is running lots of tests on the various interfaces/ports of a newly plugged modem; also, during connection the "Network Manager" attempts to get regular diagnosis updates from the device.

This all may or may not succeed - in the latter case often making the modem unresponsible ...

My advice is to use other and possibly more simple software if you run into trouble, like wvdial or others. While you are losing a bit of convenience and some features, you may gain a more reliable way of connecting (and disconnecting).
