Hello,
we had install usb_modewitch via

apt-get install usb-modewitch

And after that we had unplugged and plugged again our HUAWAI E3531i-2 3G into our raspberry and run lsusb. But we only can see:
Bus 001 Device 012: ID 12d1:1f01 Huawei Technologies Co., Ltd.

It seems no effect...

Could anyone help please?

[LOM]

I don't know how old the version of usb_modeswitch you got from your apt-get, you'll have to be a bit more specific about what you have installed and from where.

[SeLi]

Hello,
i will try.
As i told here I had install USB_ModeSwitch via
apt-get install usb-modeswitch

Version after run usb_modeswitch --version:
Version 2.2.0

We want to use HUAWEI E3531 on Raspberry PI 3. It seems also USB 2.0.

If i check with lsusb we get:
Bus 001 Device 022: ID 12d1:14dc Huawei Technologies Co., Ltd.

But we need1506

Because we try to follow that instructions: https://www.howtoforge.com/tutorial/how ... ms-server/

But we can't setup SMS Tool if it will not change to 12d1:1506 .

We had follow instructions but won't work after re insert usb dongle HUAWAI E3531 it will not change to 12d1:1506 .

How we can solve?

Could you help to do this please?

[LOM]

You can not choose the id after switching, that is decided by the modems firmware.
The modem type you have can not switch to 12d1:1506, if you need that then you'll have to find and flash another firmware for it.

[SeLi]

Hello,
which Modem can switch to that? Could you let me know please ? Or did you know a easy way for that modem? Hope you can help.

A first primer is available here (created by LOM if I'm not mistaken):

Hello,

thanks for fast replay.
As I can see it will work with:

http://www.amazon.de/Huawei-E3131-Surfs ... s=e3131s-2

Could you please compare and let me know if it is true?

[Josh]

Sorry, with all the variants of firmware around there is no guarantee whatsoever that you will get the correct one - unless you ask the seller.

[SeLi]

Hello,
sorry that I am asking but I am newbe...
I cant understand, I need mode 1506 but i dont know which device I should order and where i can get firmware for that.
I really dont know...

Could you please help?

I need plugin usb modem into raspberry pi 3 to get mode 1506...

[Josh]

See the table that I linked in a previous post.

There is a column that gives the USB ID in modem mode ("Modem Id"). Do a text search on that table and look for "12d1:1506". This gives you several lines with the modem model name in the first column.

[SeLi]

Hello,
yes I had seen.
I also read that the issue about:

Bus 001 Device 022: ID 12d1:14dc Huawei Technologies Co., Ltd.


Will build because raspberry are install via NOOBS....

So did you know any workaround?

That we can change Bus 001 Device 022: ID 12d1:14dc Huawei Technologies Co., Ltd. to 1506 ?

[Josh]

What do you mean by "workaround"?

As LOM has said already:
There is no way you can force a modem to a certain ID !!

You should really learn what sort of ports the SMS software wants (serial, ethernet, qmi, mbim etc.).
The "1506" product ID is just an example - just what the creators of the HowTo are seeing on their modem.

There is a fall-back mode for older Huawei modems which provides only standard serial ports. If you need these, create a custom mode-switch configuration file and use this inside:

Code: Select all
