Hello everyone,
I'm trying to connect tata docomo 3g dongle to my arm board (which has linux 2.6.32), steps i have done are as follows:

1-> cross compiled usb_modeswitch to arm board and kept it inside /bin/ directory of my board.
2-> i dont know what to do or how to use usb_modeswitch_data which i downloaded from http://www.draisberghof.de, i have copied usb_modeswitch.d inside /etc/
my device product id is 0x0154 and vendor id is 0x19d2

i have this inside /etc/usb_modeswitc.d/19d2:0154


# ZTE MF190 (Variant) and others
# ZTE MF190 (Variant) and others
TargetVendor=0x19d2
TargetProductList="0017,0117,2003"
StandardEject=1

and when i run this usb_modeswitch

./usb_modeswitch -v 0x19d2 -p 0x0154 -V 0x19d2 -P 0x0117 -M 55534243123456790000000
00000061b000000020000000000000000000000

result is

Take all parameters from the command line


* usb_modeswitch: handle USB devices with multiple modes
* Version 2.2.0 (C) Josua Dietze 2014
* Based on libusb1/libusbx

I'm sure you will get a better understanding of how to use usb_modeswitch and its data package if you put some bit of an effort into reading the "How-to's" on the main usb_modeswitch web page:

http://www.draisberghof.de/usb_modeswitch/#usage

http://www.draisberghof.de/usb_modeswitch/#install

I guess that your dongle switches into an id which is not 19d2:0117 but you would had known what it switched into if you had followed the instruction from the usb_modeswitch output:

-> Run lsusb to note any changes. Bye!

Hi LOM, actually i'm using a bit old busybox in my board so could not use lsusb.

Then try with either cat /proc/bus/usb/devices or cat /sys/kernel/debug/usb/devices

It's not quite possible to run this:

./usb_modeswitch -v 0x19d2 -p 0x0154 -V 0x19d2 -P 0x0117 -M 5553424312345679000000000000061b000000020000000000000000000000

and then get this:

DefaultVendor= 0x19d2
DefaultProduct= 0x0154
MessageContent="55534243123456780000000000000011062000000100000000000000000000"

I think you might have to sort out your logs ...
