USB_ModeSwitch

Posted: **01 Sep 2012, 13:41**

hello guys.
I was trying to make a Huawei E173s-1 modem work on embeded linux these days.
I have tested it on windows 7 and fedora 16, it works well.

my kernel version: 2.6.34

Code: Select all

#uname -a
Linux  2.6.34 #3 SMP Sat Sep 1 14:41:51 CST 2012 armv7l GNU/Linux

the usb_modeswitch version:

Code: Select all

#usb_modeswitch --version

 * usb_modeswitch: handle USB devices with multiple modes
 * Version 1.2.3 (C) Josua Dietze 2012
 * Based on libusb0 (0.1.12 and above)

 ! PLEASE REPORT NEW CONFIGURATIONS !

the command "lsusb" is not configured with the busybox I used, so I print the file /proc/bus/usb/devices.

plug in the modem first time , the print is :

Code: Select all

it seemed the switch not finished, and the modem was recognized once more, and the idProduct changed from 0x1c0b to 0x1c05.

And now the content of file /proc/bus/usb/devices is:

I tried to add one line in "linux-kernel/drivers/usb/stoarge/unusual_devs.h",

Code: Select all

UNUSUAL_DEV(  0x12d1, 0x1c0b, 0x0000, 0x0000,
"HUAWEI MOBILE",
"Mass Storage",
US_SC_DEVICE, US_PR_DEVICE, usb_stor_huawei_e220_init,
0),

and add the corresponding lines in "linux-kernel/drivers/usr/serial/option.c", it did not work either.

Can any body help me ? thanks in advance.

to add on, I have set "EnableLogging=1" in "\etc\usb_modeswitch.conf", but I can not find the right log file in "/var/log/" folder, I don't know why.

How did you come to that conclusion?

Did you read the explanations on the main documentation page of usb_modeswitch?

You need to install the data package as well. Your modem is fully supported since 2010. No need to tweak the "option" driver, the usb_modeswitch installation will add the USB ID to the driver 'on-the-fly'.

the product id changed from 0x1c0b to 0x1c05, but the device nodes /dev/ttyUSB* did not show up.
and the following was added into /proc/bus/usb/devices:

I read the documentation of the main page for times, I think I followed the key points.

I use "busybox + mdev" in my system, so
Is udev essential for usb_modeswith when using in command line mode ?
"usbserial" and "option" must be configured as model in kernel, right ?

So the mode switch completed fine, but no driver was bound.

johnwayne wrote:I use "busybox + mdev" in my system, so

It is not essential for the actual mode switch, but the wrapper which is usually started by udev takes care about the ad-hoc driver binding if the modem is not known to the driver yet.

johnwayne wrote:"usbserial" and "option" must be configured as model in kernel, right ?

They can either be compiled into the kernel or separate as modules. To operate the modem, they are of course essential.

To add a device ID "on the fly" to the driver, do this:

Code: Select all

# echo "12d1 1c05" > /sys/bus/usb-serial/drivers/option1/new_id

If you don't have that directory and file, you know that the driver is not active.

I got the device nodes by

Code: Select all

echo "12d1 1c05" > /sys/bus/usb-serial/drivers/option1/new_id

Thank you very much, Josh. Thanks for your patience.
