Oops, I am very sorry. :oops: I didn't even notice that they were that large!

By the way, I have the kernel 2.6.32-27-generic, nonetheless I get the error messages.

What do you mean by "look at the time more closely"?

What I mean is that it would probably help to activate the switching right upon plug-in, before the storage subsystem has a chance to kick in.

For this, it would be advised to prepare everything for an automatic switching. That means creating a config file and and adding an udev rule to "/lib/udev/rules.d/40-usb_modeswitch.rules".

Ok, it makes a lot of sense. What should I do?

You can easily work with an existing config file in "/etc/usb_modeswitch.d".
Copy the file "12d1:1001" to "12d1:1009", then edit the new file and change the "DefaultProduct" value accordingly.

Next, edit the file "/lib/udev/rules.d/40-usb_modeswitch.rules" and add a line for your device. Have a look at all the other lines, it's very straightforward to do.

Dear Josh,

I've just tried to edit those files, I restarted my system and then I plugged my mobile phone. Still I get the same errors:

I assumed that it should have been now mounted as a USB modem without any additional commands, therefore I haven't tried to switch it manually.

Is it right?

Apart from the errors, what does "lsusb" say ? Any changes in the ID ?

And what about "lsusb -v" - did the interfaces change in any way ?

Actually, something changes!

Before editing the files discussed two posts ago, lsusb -v gives:

This is what I added in 40-usb_modeswitch.rules (before ' LABEL="modeswitch_rules_end" '):

ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1009", RUN+="usb_modeswitch '%b/%k'"

Any ideas?

Ahaaa - same ID but different interfaces after switching. Unusual for a Huawei device, but not unusual overall.

So your "12d1:1009" config file should look like this [edited, correction]:

Code: Select all

DefaultVendor= 0x12d1
DefaultProduct=0x1009

TargetClass=0xff

HuaweiMode=1

CheckSuccess=20
Or as a command line:

Code: Select all

usb_modeswitch -v 0x12d1 -p 0x1009 -C 0xff -H

Switching works, now the driver has to be loaded.

You will reliably get serial ports automatically if you use program version 1.1.6

Holy crap!!! It works!!!

This is what I did. I purged the previous installation of usb-modeswitch and the data package, so to refresh the configuration files I edited some time ago. Then, I manually compiled the 1.1.7 version of usb-modeswitch. I noticed that there is a rule for my Huawei V725.

When I plug in my mobile I get:

D'you see? There is something about a GPRS modem. Also, I find the devices /dev/ttyUSB0 and /dev/ttyUSB1.

Finally, without any call to usb_modeswitch, I run wvdial and I am connected! Thank you so much!!!!

That's how it is supposed to work - fully automatic ...
