Huawei E3531 on embedded device

Hi,
I try to figure out how to connect my Huawei E3531 dongle on my embedded device. This is a UDOO board with a custom Linux built from Buildroot. In the kernel, I checked those options :
Code: Select all
-Device Drivers --->
- Network device support --->
- PPP
- USB support --->
- <*> USB Modem (CDC ACM) support
- <*> USB Serial Converter support -->
- USB Generic Serial Driver
- USB FTDI Single Port Serial Driver
- USB Debugging Device
And with Buildroot, I installed those packages :
Code: Select all
- Target packages --->
- Hardware handling --->
- usb_modeswitch
- usb_modeswitch_data
- usbutils
- Networking applications --->
- pppd
- wvdial
At first, when I run this command :
I get this output :
Code: Select all
Bus 002 Device 004: ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter
Bus 002 Device 003: ID 12d1:15d2 Huawei Technologies Co., Ltd.
Bus 002 Device 002: ID 0424:2514 Standard Microsystems Corp. USB 2.0 Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
My question is how to switch this dongle into modem mode ? It seems that I should write a config file in /dev/usb_modeswitch.d/vid:pid but I cannot figure out what I should write into. I saw a MessageContent field but I don't know where it comes from.
So first, I tried a simple command with a "random" MessageContent found somewhere :
Code: Select all
usb_modeswitch -W -v 12d1 -p 15d2 -n --message-content 555342437f0000000002000080000a11062000000000000100000000000000
I get this output which is absolutely not clear if it worked or not :
Code: Select all
Take all parameters from the command line
* usb_modeswitch: handle USB devices with multiple modes
* Version 2.0.1 (C) Josua Dietze 2013
* Based on libusb1/libusbx

I guess it worked because the
lsusb command shows :

The product ID changed from
15d2 to
15d3.
I should be able to write a wvdial config file so :
Code: Select all
# wvdialconf
Editing `/etc/wvdial.conf'.
Scanning your serial ports for a modem.
Sorry, no modem was detected! Is it in use by another program?
Did you configure it properly with setserial?
Please read the FAQ at http://alumnit.ca/wiki/?WvDial
It seems that my dongle isn't configured as a modem

Show me the output from lsusb -v -d 12d1:15d2 before you switch the device and from lsusb -v -d 12d1:15d3 after switching.
Your dongle has a direct ethernet interface but may also have an old-fashioned ppp dialup interface.

Your dongle has a dual mode firmware where you have the Win8 mbim protocol
in 12d1:15d2 (mbim in config #2, the usual virtual cd-rom containing windows drivers and connection manager in config #1)
while 12d1:15d3 is Win7/XP compatible mode.
Interface usage:
12d1:15d2
-----------
Cfg#1
MI_00 USB Mass Storage Device
Cfg#2
MI_00, MI_01 3G Network Card (MBIM)
MI_02 USB Mass Storage Device
12d1:15d3
------------
MI_00 HUAWEI Mobile Connect - 3G Modem
MI_01 HUAWEI Mobile Connect - 3G Network Card (NCM)
MI_02 HUAWEI Mobile Connect - 3G Application Interface (diag)
MI_03 HUAWEI Mobile Connect - 3G PC UI Interface (at cmd)
MI_04 USB Mass Storage Device
MI_05 USB Mass Storage Device
The dongle will start as 12d1:15d2 config #1 and usb_modeswitch will select config #2
if the linux cdc_mbim driver is present in the system, otherwise it will send
the switch message to bring the dongle over to 12d1:15d3.
There is a ppp dialup modem interface in 12d1:15d3 for which you need the linux serial driver named option.ko together with usb_wwan.ko and usb-serial.ko in order to create /dev/ttyUSB0..2 where ttyUSB0 will be the modem device.
If you decide to use the direct ethernet interfaces then you will need other drivers like
cdc_ncm, cdc_mbim, cdc-wdm, communication libraries (libmbim) and linux NetworkManager.

lsmod will show you which modules has been loaded into memory,
modprobe modulename will load a module into memory.
The modprobe order for ppp serial dongles using the option driver is usb-serial, usb_wwan, option.
Are you on a very old kernel version?
Option supports your dongle from around kernel 2.6.38 and up.

I have no module loaded. I didn't compile the drivers as modules but as built-in features.
My kernel version is 3.0.35.
Re: Huawei E3531 on embedded device

by LOM
I downloaded 3.0.35 to verify that your device is supported and I see the problems now.
/drivers/usb/serial/option.c contains:
Code: Select all
{ USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, HUAWEI_PRODUCT_E353, 0xff, 0x02, 0x01) }, /* E398 3G Modem */
{ USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, HUAWEI_PRODUCT_E353, 0xff, 0x02, 0x02) }, /* E398 3G PC UI Interface */
{ USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, HUAWEI_PRODUCT_E353, 0xff, 0x02, 0x03) }, /* E398 3G Application Interface */
which is a matching based on vid:pid + interface attributes.
There is no reason to have the pid matching and that has been changed in later versions
of option, here kernel 3.2.30:
Code: Select all
{ USB_VENDOR_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x01) },
{ USB_VENDOR_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x02) },
{ USB_VENDOR_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x03) },
You'll have to update your source code, backport from a later version.

I compile the kernel using the sources given by UDOO :

Last commit on July 2014.
I'll update my code.

Tell them that kernel 3.0 is depreciated, is dead.
It does not get any official updates or bug fixes, therefore it is no more.

OK, I juste updated the line
Code: Select all
#define HUAWEI_PRODUCT_E353 0x1506
to
Code: Select all
#define HUAWEI_PRODUCT_E353 0x15d3
After running usb_modeswitch I get :
Code: Select all
[ 83.070870] usb 2-1.1: USB disconnect, device number 3
[ 84.590746] usb 2-1.1: new high speed USB device number 5 using fsl-ehci

And the wvdialconf command runs perfectly !
So now I'm gonna have a look on wvdial and it's configuration file.
Thanks a lot
