Once the switch has happened, do this:

Code: Select all

# modprobe -v option
# echo "15eb 7152" > /sys/bus/usb-serial/drivers/option1/new_id
Also, check the ttyUSB ports that are created for the ones that contain an endpoint with transfer type "Interrupt". The easiest way to do that is "lsusb -v -d 15eb:7152"
now i am assuming these steps are to be done after eject /dev/sr1. so wvdial and pppd gives the same result, this time slower and unresponsive.
and all endpoints have bulk transfer type.

if i do these steps after usb_modeswitch, same things happen except this time there is only ttyUSB0.
thanks

I am really out of suggestions here. I suspect you may have a hardware or driver problem with your USB host ...

I am about to add this device to the data package, to be released soon. Maybe someone else can make this thing work.

If you want you can give me your name (or any nickname of your choice) via PM or mail, and I'll include you as the contributor of this device in the reference file.

Continuing (with similar modem)

Post by jrocky » 03 Sep 2012, 21:14

I posted in this thread (instead of making a new one) because I have a similar modem as tricky.

I can switch just fine, using the -M "5553424312345678000000000000061b000000020000000000000000000000". However after switched, the modem would not let me connect to the network.

My OS is Ubuntu 12.04 (amd64), running Linux kernel version 3.2.0-29-generic.
The CDMA modem is branded as "Cyrus MC400", but after switched become "China TeleCom CBP7.1".

This is the usb_modeswitch version that I used:

Code: Select all

$ usb_modeswitch -e

 * usb_modeswitch: handle USB devices with multiple modes
 * Version 1.2.3 (C) Josua Dietze 2012
 * Based on libusb0 (0.1.12 and above)

 ! PLEASE REPORT NEW CONFIGURATIONS !
This is output of lsusb before switch:

This is how I switched the modem:

Code: Select all

$ sudo usb_modeswitch -v 15eb -p 7153 -V 15eb -P 7152 -M "5553424312345678000000000000061b000000020000000000000000000000"

The modem switched OK.

Note: there is no endpoint with transfer type "Interrupt".

Next, I load the usbserial kernel module:

Code: Select all

$ sudo modprobe usbserial vendor=0x15eb product=0x7152
This is a portion of /var/log/syslog that shows what happened when the modem was plugged, then when the modem was switched, then loading the usbserial kernel module.

To summarize the log:
  1. Modem plugged
  2. Modem switched
  3. usbserial kernel module loaded
  4. modem-manager kicks in (ttyUSB0 appears)
  5. modem-manager tries to connect with network ... and failed
  6. After a moment, modem-manager SEGV (I do not know what that means)
  7. modem-manager restarted (ttyUSB0 appears again)
  8. modem-manager tried to connect to network again (and failed again)
  9. SEGV again
  10. and so on
So, switched OK, but cannot connect to the CDMA network. Any idea, everyone?

You can use the latest data package release from this site to bring your usb_modeswitch installation up-to-date. Your modem is included and the driver will be loaded automatically.

There is one difference though: it will probably work better because it binds the "option" driver which is a serial driver with optimizations for wireless modems. Kernel programmers tend to discourage people from using the generic "usbserial" module.

I installed the newest data package (usb-modeswitch-data-20120815), and the program package (usb-modeswitch-1.2.4). Now the switch happens automatically after plugging the modem, and option kernel module is also loaded automatically.

However, the modem still would not connect to the CDMA network. The most obvious error in the log being SEGV on modem-manager.

This is what I did, from beginning to finish:

1. I uninstalled the preinstalled usb_modeswitch.

Code: Select all

sudo apt-get purge usb-modeswitch usb-modeswitch-data
2. I installed the library and application required to compile usb_modeswitch.

Code: Select all

sudo apt-get install libusb-dev tcl
3. Got usb_modeswitch source packages.

Code: Select all

wget http://www.draisberghof.de/usb_modeswitch/usb-modeswitch-1.2.4.tar.bz2
wget http://www.draisberghof.de/usb_modeswitch/usb-modeswitch-data-20120815.tar.bz2
4. Extracted the packages.

Code: Select all

tar xf usb-modeswitch-1.2.4.tar.bz2
tar xf usb-modeswitch-data-20120815.tar.bz2
5. Compiled and installed.

Code: Select all

cd usb-modeswitch-1.2.4
sudo make install
cd ../usb-modeswitch-data-20120815
sudo make install
6. Restarted the computer (I do not know if this is required or not, but I did it anyway).

7. This is just to confirm the version of the usb_modeswitch.

Code: Select all

$ usb_modeswitch -e

 * usb_modeswitch: handle USB devices with multiple modes
 * Version 1.2.4 (C) Josua Dietze 2012
 * Based on libusb0 (0.1.12 and above)

 ! PLEASE REPORT NEW CONFIGURATIONS !
8. Lastly, I plugged the modem. Finish.

Now the NetworkManager shows that CDMA connection can be made, but upon clicking the listed connection, a 'disconnected' message appears. This is the portion of /var/log/syslog that is relevant with the problem:

Looks like the problem is not in usb_modeswitch.

This looks indeed like a case for the "modem-manager" maintainer. There is a veritable crash in that program which should not happen no matter which hardware is thrown at it.

I suggest filing a bug; AFAIK the development for "mm" and "NM" is done at Redhat.

Thanks, Josh. I filed the bug as you advised.

In GNOME Bugzilla:
Bug 683525 - China TeleCom CBP7.1 causes modem-manager to crash (SEGV)
