Hello all,
Just joined this forum after posting a thread in LinuxQuestions.org:
http://www.linuxquestions.org/questions ... -a-810361/

Bought a Huawei 1261 and am trying to get it to work in Hardy 8.04 (kernel 2.6.24-16-386). I installed usb_modeswitch from two sources:
http://www.draisberghof.de/usb_modeswitch/
http://packages.debian.org/search?keywo ... modeswitch

Both of them installed successfully. But neither of them detect my modem.

The contents of the usb_modeswitch.conf file are:

When I run usb_modeswitch -c /etc/usb_modeswitch.conf I get:

Disable any rules in /lib/udev/rules.d affecting your ID (12d1:1446).

Be sure to run as root or with sudo.

Try this: usb_modeswitch -I -W -c /etc/usb_modeswitch.conf

Tell me what happens.

Thanks for your response.

The only file in /lib/udev/rules.d was 40-usb_modeswitch.rules. Anyway, there was a line regarding Huawei 12d1:1446 that I commented out.

I ran the command you suggested as su and this is what I got:

The device has changed from 12d1:1446 to 12d1:140b. So does this mean it has been detected?

I'll try the wvdial and see what happens.

Thanks again Josh.

The modem has switched but there is no driver assigned to it yet.
Your kernel is quite old so the "option" driver doesn't have the ability to add new USB IDs on the fly. You have to use the generic serial driver which is generally not recommended but may work. The other possibility is to change the source code of the "option" driver and add your device ID.

After switching do a "modprobe -v usbserial vendor=0x12d1 product=0x14ac". This should give you ttyUSBx ...

Hello, I got my device working using Josh's comments. Thanks to the coders and the posters!

Huawei EC1262 for Reliance Netconnect Broadband+, India.
On two machines:

1) modprobe -r usb_storage
2) modprobe -r usbserial
(a -d switch ought to do the same thing)

For completion:
Steps 1,2 and 3 can indeed be done together with a -d option.
usb_modeswitch -d -I -W -c /etc/usb_modeswitch.conf

And after connecting I have to add the route information to use the connection.
route add default gw the-remote-ip

Thanks for the responses.

Travelling at the moment and don't have my linux box with me. Will try out the suggestions and get back to you by the weekend.

Thanks again.

Sorry for the late response. Just got back home.

I tried
Quote:
modprobe -v usbserial vendor=0x12d1 product=0x140b

as suggested but still no /dev/ttyU*.

Thanks.

After the device has switched ("lsusb") and after running the "modprobe" line (you should see "insmod ..."), do a "dmesg" and post it.

If you don't see "insmod <something>" when trying to load usbserial, then the module may be loaded already; in that case it has to be unloaded and reloaded to add the new device ID.

Thanks Josh, it worked.

I didn't get the insmod command the last time I tried. So I rebooted so refresh the system and ran the command again.
This is the dmesg output:

Internet works fine and I am sending this post using my Ubuntu box.

Thanks very much Josh, particularly since I was delaying trying suggestions out. I was worried I would have to upgrade my Ubuntu.

hello Josh,
First of all,thank you very much.
I have the same problem with shivkiyer. I have tried out your suggestions step by step.when i execute 'modprobe -v usbserial vendor=0x12d1 product=0x1001 'command ,i saw the 'insmod ...',but i still have no /dev/ttyU*.
i am a nev linux learner,thank you for your help!
PS:My linux OS is Redhat Enterprise AS4 Update5,the kernel is 2.6.9-55,usb_modeswitch is usb-modeswitch-1.1.6 and usb-modeswitch-data-20101222.

Phew, that is a very old kernel. Or rather, a very old system. I'm not even sure it will automatically add new device nodes in /dev dynamically. You might have to create those nodes manually.

What are the ~30 last lines of "dmesg" output immediately after you run the "modprobe" command ?

I think you could see for yourself that the driver was correctly loaded and seems to do its job.

If you still don't see new devices in the "/dev" folder, there might be an issue with your hotplug system. To be frank, it is ill-advised to use this distribution for the first steps with Linux. Why not use one of the up-to-date and user-friendly mainstream distributions?

pty_master /dev/ptm 128 0-1048575 pty:master
unknown /dev/tty 4 1-63 console
