/lib/udev/rules.d for imx6 sabresd board for establishing network for usb modem

[bandarulavanya]

Hi All,

I am trying to use the usb modem to my board, i can able to do usb_mode switch to convert from CD-ROM to modem.

LOG for this

I connected modem to usb host :

Now i am inserting the modules :

insmod usb-storage.ko

insmod cdc_ether.ko

insmod  rndis_host.ko

insmod usbserial.ko

Log is here:

How we can establish the connection?

In my PC(kernel version -3.2.0-91-generic-pae ) i tried it by disabling automatic usb_modeswitch in usb_modeswitch.conf file in /etc folder.

i did

sudo usb_modeswitch -v 0x1bbb -p 0xf000 -V 0x1bbb -P 0x0017 -M "55534243123456788000000080000606f50402527000000000000000000000"

after this immediately it is converting to modem and connection is establishing.

similar to this can we get in board also ?

can i get udev/rules.d  and supported files for imx6 sabresd board ?

Thanks & Regards,

Hi Bandaru

seems driver for this device is not correct or from other linux

distribution/version. It may be suggested to ask from vendor of this

usb modem updated driver for specific linux version which is used in the case.

Best regards

Hi igorpadykov,

Actually i am asking about this connection of networking is happening automatically bcz of udev/rules.d in PC that how we can do and what is the exact config file they are using.

For usb_modeswitch they are using "40-usb_modeswitch.rules" similarly which file they are using for setting network connection.

Thanks & Regards,

Lavanya

Hi  Lavanya,

After creating eth0 node do " ifconfig eth0 proper-IP up " or try with

" udhcpc -i eth0 -b -t 10"

then you will get the IP and then "ping google.com"  or global ip like 192.168.1.1

Thanks & Regards,
