Hello!

First I want to say hello to everybody on this forum, first topic for me here!

I have a modem (D-50) that connects to the nordic mobile telephone network (www.nmt.net), there is files included for Linux.
My friend compiled this for OpenWrt Kamikaze 7.09, but it's not working! The file runs well but result is "Fail SwitchMode"

A guess that this light linux version missing something...?
Anybody that tested NMT-450 D50 modem on other linux that can help to get it running in openwrt?

I have a Asus 500gP with Kamikaze 7.09 Kernel 2.6

Want to add some info of tests I made.

Tried both Kamikaze 2.4 and 2.6 but the file RDEVCHG compiled for openwrt stops really quick, "Fail SwitchMode".
Tested to run files included (original) on USB-Modem in Ubuntu Live-CD, RDEVCHG runs for a while and finds modem and the device is added to /dev/.

Anybody that can look on the sourcecode in my earlier post, should that work on a OpenWrt??? Or must it be changed?

Many thanks for help!

Hello Daniel,

I had a quick look to code what you had sent.
It looks like program is just sending SCSI command to all scsi generic device files to perform some kind of switch to modem mode. And then it verifies whether there appeared the requested new USB devices... via lsusb command.
Please try to type: lsusb at your command prompt to see whether it is available ( so maybe it successfully performs switch but it just didn't found the lsusb command)
Please post here lsusb & dmesg output.
After it performs switch you need to load usbserial kernel module (maybe it will be done autoamticaly). And then you can start PPP to do the internet connection.
If the OpenWrt doen't have automatic support for these devices (I'm really not sure about). You will need to follow few steps.
Please check gentoo wiki regarding maybe similiar modem:
http://gentoo-wiki.com/HARDWARE_HUAWEI_ … _USB_MODEM

Cheers,
Vladimir.

Thanks for help, vlx!

Now I have done the tests and here is the result. How do I load usbserial?
And how to make PPP? Original with the modem it was a file to execute after modem switch but it use wvdial? And that command is not working on openwrt?
I put the included code in the bottom of this post!!!

How do I load usbserial to be used with the found modem?
And how to make PPP under OpenWrt?

Original with the modem it was a file to execute after modem switch but it use wvdial? And that command is not working on openwrt?
