MD400 (Sonyericsson HSUPA USB modem) I need some help! - Page 6

Post by **Josh** » 05 Jun 2009, 23:33

O.K., thanks for the input; I changed the "MD 400" entry in the config file. The "TargetClass" was a leftover from the first experiments.

I did all testing for the new proc on the command line so this obviously escaped my attention. Blame it on aging ...

I'm a bit curious on automating this. Should I just put a roughly 5-7 second sleep in my shellscript before I make it run usb_modeswitch again (making sure it has a bit of time to load drivers and whatnot) or can I just call them twice in rapid succession?
To avoid the modem switching back that is, I didn't see information on this under the guide for automation.
I could trial and error but I'm also quite curious on how this actually works.

The device needs to vanish and be back with the modem part before sending the switch command again.

On my system it switched back after annother 30 seconds. During that time the command should be repeated; so on your system anything between 7 and 27 seconds should work.

Josh: When you tested MD400, which kernel module did you use ? I have been able to get the switch to work fine but no driver is ever loaded. I use Gentoo so I compile my kernel from source. I use gentoo-sources and it does not contain Carl's patch for mbm driver.

jbn: The output from your dmesg or /var/log/messages after the switch to modem configuration might help me find out the right module, especially if you posted the output of your lsmod too

The MD400 switches to CDC ACM mode which has a dedicated USB device class (2 and annother interface with 9). It should bind automatically if the driver is present.

In the kernel menuconfig the entry reads:
"USB Modem (CDC ACM) support"

Hello!

Recently received a MD400 that I try to use with Ubuntu 9.04. I have installed usb_modeswitch 1.0.0 (Version printed out is wrong BTW).

When calling usb_modeswitch one time I get:

Should I issue a new call to usb_command withing 10 seconds before the modem is recognized as a mass storage again?

I have also tried:

Code: Select all

sudo ./usb_modeswitch && sleep 7 && ./usb_modeswitch

After that I see the network manager trying endlessly to connect without success.

Please let me know if I should provide further information. Any help would be appreciated!

Best regards,
Peter Carlsson

Your configuration is fine. You need to call USB_ModeSwitch only once. As soon as the ttyACM devices pop up, you are in modem mode. Don't do anything else.

The other posts in this topic were about debugging with a previous version.

There was a missing comment sign in the config file; it's fixed now so you don't get the "ignoring MessageContent" line anymore.

Use the latest version.

Post by **Josh** » 09 Jun 2009, 00:36

Oh, and I fixed the version number in 1.0.1.

Thanks for the hint!

PeterC · Post by **PeterC** » 09 Jun 2009, 07:01

Thanks for the quick response!

That's good to know that the switching works. I only have to figure out why it doesn't connect.

Maybe someone on this thread can help me? I live in Sweden and need help to connect to Bredbandsbolaget.

Best regards,
Peter Carlsson

Post by **Josh** » 09 Jun 2009, 08:40

I googled for you

...

... and found a good overview (as far as my guessing of Sverige tells me) here:

http://wiki.linuxportalen.se/index.php/Mobilt_bredband

There is probably nothing about Bredbandsbolaget access but my guess is all you need for that is the correct Access Point (APN) and your SIM card.

I have really used Google but this URL was new to me and it seems that the (default) APN I had is wrong. I am at work right now but will try as soon as I get home.

Thanks for the great help!

Home from work!

Noticed that if I call usb_modeswitch (version 1.0.0) one time it seems like the modem switches back to USB storage again after a few seconds. This is in Ubuntu 9.04 and I also see that two file windows (one for each USB partition) are opened. Maybe this has something to do with Ubuntu automounter, but why is my modem switching back?

Below is the log from where I issue the usb_modeswitch command:

Post by **Josh** » 11 Jun 2009, 21:09

I can see nothing switching back ...

The ttyACM0/1 devices are not removed. What you get are NEW storage devices after switching (card reader and probably the "driver disk" again

I have now disabled automount in Ubuntu 9.04 and now the USB storage drives does no longer show up.

Actually, I think the switching is successful and the NetworkManager is trying to connect on /dev/ttyACM0 and /dev/ttyACM1 without success. The log file (not available at the moment) says something about:

Code: Select all

(dev/ttyACM0) GSM puk secret required

Do I have to enable the SIM card before using it or have I failed too many times with my PIN code that I need to unlock the card using the PUK code?

This has nothing to do with USB_ModeSwitch, but someone on this forum might have an answer.
