Hi guys,
I got the E3131 switched like this:

but I find neither a /dev/ttyUSB* device nor does ifconfig -a show something new.
What should I see if the switch to modem had worked?
Can I switch the switched device further, like :
install_CD -> install_CD + SD card -> SD Card + UMTS dongle ?

What linux kernel module / capability has to be present to recognize a popping up UMTS stick?

thx in advance for input

You can not switch the device further, 12d1:1506 is a usb id for a device after it has switched.

One of the drivers you'll have to load is named option, it is a serial port driver. The device does also have a direct ethernet interface which will be driven by one of:
qmi_wwan
cdc_ncm
cdc_ether

I need to see the output from lsusb -v -d 12d1:1506 in order to tell you which kind of direct ethernet driver your device needs.

Thx a lot for clarifying. Problem is that I'm talking about an embedded device on ARMv7.
However, the good guys did publish the GPLed linux source, as they are obliged to.
And their config.linux says the following with regard to usb and networking:

Code: Select all

#
# USB Network Adapters
#

# CONFIG_USB_KAWETH is not set
# CONFIG_USB_PEGASUS is not set

# CONFIG_WIFI_CONTROL_FUNC is not set
# CONFIG_BCMDHD is not set
CONFIG_HOSTAP=m
# CONFIG_HOSTAP_FIRMWARE is not set
CONFIG_WILINK_PLATFORM_DATA=y

So no NET_QMI_WWAN, but NET_CDC_NCM and NET_CDCETHER are part of the kernel (no modules).

Second issue is lsusb -v on the embedded device doesn't output more than plain lsusb.

I'll try to see what the Raspi2 says to lsusb -v (after switching the decive, of course. Should be much more versatile).

Meanwhile, this is what USBTreeView under Windows7 64 has to say.
maybe you can deduct the respective linux driver needed from all this info:

extra question1: which kernel config option controls wherter the "option" usb module will be created?

extra question2: assuming cross-compile infractruture and embedded linux kernel source tree installed somewhere,
Is it possible to change a kernel config_option form N to M, build the module(s) and load these freshly build modules into the unmodified embedded linux kernel, (in his config these configoptions were set to N)?
Sort of post-create the modules only and feed them to the unchanged kernel.

The 6 interfaces of your device are:

MI_00 HUAWEI Mobile Connect - 3G Modem
MI_01 HUAWEI Mobile Connect - 3G Network Card
MI_02 HUAWEI Mobile Connect - 3G Application Interface
MI_03 HUAWEI Mobile Connect - 3G PC UI Interface
MI_04 USB Mass Storage Device
MI_05 USB Mass Storage Device

The option driver will create 3 ttyUSB devices for interfaces 0, 2, and 3, the storage driver will take care of interface 4 and 5.

Interface 1, the network card, needs huawei_cdc_ncm, cdc_ncm, usbnet, and cdc-wdm.
You will need a recent kernel, 4.4 or 4.5 for it.

1. CONFIG_USB_SERIAL_OPTION (depends of usbserial and usb_wwan so you must build those as well).

2. Yes you can build kernel modules separately but they must be built from exactly the same source as the kernel was built from.

Thx a lot for that wealth of insight. If I take the linux.config file as a blueprint of what capabilities my kernel version has and the options set to "N" as the modules I could build it appears that I'm screwed:

I can't find neither kernel option usb_serial_option, usb_wwan, nor huawei_cdc_ncm.
So neither the usbttys nor the network card interface will ever show up, kernel too old.

Do you see any way to get that 3G dongle to work under kernel 3.4.11?

edit:
I found option.c in the linux source tree, togheter with usb_wwan and usb_serial!
Although its only 3.4.11!? So I'll try and setup that cross compile environment and add Vendor Id and Product Id into option.c.
Maybe that'll work..?

Have you tried adding supplier Id and product Id to option.c. yet???? Was it successful?
