Hello,

I have added package as "usb-modeswitch", although it could be related to Modem Manager, Network Manger.. sorry, I dont know what else to put. If you can be specific on what is required, I will be happy to provide.

My USB 3g is Huawei E173 and I think I got the same problem.
It works on Xubuntu 11.10 but after I upgrade to 12.04 it stops working.

I think the problem is in the usb_modeswitch_dispatcher.

+void check_driver_bind (char* vid, char* pid)
+{
+ char *default_loader = MODPROBE;
+ char *loader = NULL, *id_file;
+ char *vendor_spec, *product_spec;
+ struct stat buf;
+ int i, x, status;
+ pipeline *p;
+ FILE *new_id_f;
+
+ x = lstat (default_loader, &buf);
+ if (x != 0)
+ modeswitch_log (" %s not found", default_loader);
+ else
+ loader = strdup(default_loader);
+ modeswitch_log("Module loader is %s\n", loader);

I don't know much about C++ code but I tried to find the lstat command but it doesn't exist.

Status changed to 'Confirmed' because the bug affects multiple users.

I was wrong about the lstat command doesn't exist, it's a function in C not the command. But it return negetive.
I tried stat command on my PC and here is result:
$ stat /sbin/modprobe

I found the way to fix my problem by run this command after plug usb in:
sudo modprobe usbserial vendor=0x12d1 product=0x14a8

Hope this help.

Hi all,

following Nguyen Anh Minh suggestion about the problem in the dispatcher,
I downloaded, compiled the last version and copied the new version of "usb_modeswitch_dispatcher"
over the old one.

Now every thing works correctly.

*) These are the last lines of the logfile:
Now checking for bound driver ...
 no driver has bound to interface 0 yet
Device is not in "bind_list" yet, bind it now
Module loader is /sbin/modprobe

Trying to load module "option"
 Module was loaded successfully:
insmod /lib/modules/3.2.0-23-generic/kernel/drivers/usb/serial/usbserial.ko
insmod /lib/modules/3.2.0-23-generic/kernel/drivers/usb/serial/usb_wwan.ko
insmod /lib/modules/3.2.0-23-generic/kernel/drivers/usb/serial/option.ko
Trying to add ID to driver "option"
 ID added to driver; check for new devices in /dev
 driver was bound to the device
Checking for AVOID_RESET_QUIRK kernel attribute
 AVOID_RESET_QUIRK activated

All done, exiting

*) network manager recognises sooner the new device
*) and I do not have to manually add the usbserial options. :)

*) I think that in the ubuntu version there's simply a bug when detecting the modprobe path.
Last source version in the website is 1.2.3, while in ubuntu I have 1.2.3+repack0-1ubuntu2.

*) here I have a fresh ubuntu installation with only the updates. Compiling the dispatcher is trivial, you just need to
installa libusb-dev, type make and then ./make_static_dispatcher.sh
Ok. not the cleanest way, but ..

cheers,

This worked for me also on 12.04 / 64bit - using Huawei E353 (oister/denmark).

Must be a packaging error or something :)

Any update on this ? I really dont want to manually compile and risk it getting broken.

After numerous tries, I was able to get this to work by the following

1) plug the EVDO and wait for the log to show failed as given on my opening thread

2) type "sudo modprobe option"

3) unplug and plug EVDO back in... it will show

* Now the EVDO device will be shown on the network manager and I am able to connect. Please let me know why this is happenning.

PS :: sorry for the double post, I accidently clicked on Post before I completed typing.

The problem is clear in the very first post:

...
Device not in "bind_list" yet, bind it now
modprobe not foundModule loader is (null)
Can't do anymore without module loader; get "modtools"!
driver binding failed
...

This is a problem of the C wrapper - maybe the MODPROBE macro is not correct?

usb_modeswitch will try to enable modems even if their ID is not known (compiled in) to the modem driver yet. For this it needs to load the respective module using the "modprobe" tool and then add the modem ID to it on-the-fly.

No. MODPROBE is defined to be 'modprobe' because we want to get the binary from the path. PATH should always be set since it gets retrieved from /lib/udev/hotplug.functions which defines it properly as including /sbin (the location of modprobe). This was working properly before 12.04; so if it's broken, something outside of usb_modeswitch might have changed.

If this was really broken though we'd be getting tons more reports of issues, and I should be able to see it myself, which so far hasn't been the case. I'll get back to testing it ;)

Yet it really is broken, I was confused by something else I was working on.

lstat() obviously doesn't take into account PATH, I should have known that and it should have been immediately obvious, since it's so wrong... Uploading the fix to Quantal shortly.

Bug #996664 is a duplicate of this bug

This bug was fixed in the package usb-modeswitch - 1.2.3+repack0-1ubuntu3

---------------
usb-modeswitch (1.2.3+repack0-1ubuntu3) quantal; urgency=low

  * debian/patches/dispatcher-c-rewrite.patch: correct the "search" for
    modprobe to properly figure out whether it's available from PATH.

Kindly let me know when this will be available as an update.
Also I have now seeing that the connection is getting dropped after being online for 50 min to an hour and the modem disappears from the network manager. I can get the connection back by pulling out and then plugging it back in. But again it will go after 50 min.

Pasting the last few entries from dmesg below.

Shouldn't this usb-modeswitch bug be fixed in Ubuntu 12.04 LTS?
