Hi,

Has somebody experience with cdc_ether/ndis-mode under Linux, with 3G/4G-datacards, precise huawei E398?

The HUAWEI UMTS Datacard Modem AT Command Interface Specification_V2.3.pdfhas no example. (only some small explanation to ^dialmode)

The driver hw_cdc_driver.c (module hw_cdc_driver )Version "v2.07.00.00" from December 2010 is supplied as src (GPL). It also compiles but I found no hints to the right use.

Of course I could wait until a new "mobile partner"-software is available.
But I would like to know how it works in simple words and steps, not with sophisticated graphical user interfaces hiding the interesting parts. A small script should be enough.

Regards,
Thomas Schäfer

There is also a thread in jdtech.pl describing all the way to the solution (however it is in Polish): http://jdtech.pl/2011/09/aero2-zmiany-n ... t193291386

Thank you for the hint.

AT^NDISDUP=1,1,"my_apn_name"

sets the modem online. (LED)

In my case unfortunately nothing more happens.

But now I have new keywords for further searches.

Which version of kernel do you use?
If the version is 2.6.39 or above, you should
have the ethernet device wwan0, and you should
be able to configure it via e.g. "dhclient wwan0"
(however there are problems with the destination
address of incoming packets, which I have mentioned
in the referenced post.

Which version of kernel do you use?

2.6.34.10-0.2-desktop with huawei-driver DRIVER_VERSION "v2.07.00.00"

At systems with higher kernel versions I was not able to compile.
The problem-code-line was this:

Code: Select all

#include <linux/usb/ncm.h>

If the version is 2.6.39 or above, you should...

Do you have a newer version of the driver, compatible also with kernel 3.x?


Franko Fang has answered: " For newer kernel, we are developing for it now, and will release the compatible driver some time later." ( 2011-09-08 )

I use the standard cdc_ether driver, and kernel 3.0.1 or 3.0.3
Starting from 2.6.39 it supports huawei modems.
However my modem is e173, not e398, and this may be a difference...
