- Recently bought a Laptop with Ubuntu 12.04LS(Kernel 3.2.0-39-generic) on it.
- I'm unable to `plug & use` iBall 3.5G Connect v2.0 USB DataCard
- However, on the same OS Huawei E1731 USB DataCard works perfectly 'plug & use(play)'.
- Huawei E1731 comes with separate installer(.bin) for Linux, however doesn't need manual intervention. iBall3.5G comes with only 'scripts' that I'm attaching below.
- both HuaweiE1731 & iBall3.5G have AirTel SIM but different Mobile#(MSISDN/MDN)
- both HuaweiE1731 & iBall3.5G work on WinXP(SP3), thanks to bundled drivers s/w(AutoRun)

1. After spending hours on Internet I found sudo echo 05C6 0016 > /sys/bus/usb-serial/drivers/option1/new_id
should work and give me some /dev/ttyUSBx.
2. Also cross checked TargetVendor:TargetProduct pair using SniffUSB.exe on winXP, it's 05C6:0016. dialup shell script seems to be in right direction.

PS: I did juggle with suggestions given on over a dozen websites about gnome-ppp, minicom, modprobe, usb_modeswitch etc. None of them worked out for me.

Am I right assuming that first the command sudo echo 05C6 0016 > /sys/bus/usb-serial/drivers/option1/new_id should generate some /dev/ttyUSBx dev files?

Please push me in right direction.

[D3m0N81]

I see I've to modify rules per :
http://www.draisberghof.de/usb_modeswit ... f=4&t=1114

Will check & update.

[LOM]

Adding the Target id to the option drivers new_id function is one of the last step you'll have to do, first you'll have to make the dongle switch from default mode.
05c6:f000 , the default id, is supported by usb_modeswitch since years back so your dongle ought to switch automaticall if you have usb_modeswitch installed.
Your dmesg log will in such case show an usb bus detection of 05c6:f000 which will disappear when usb_modeswitch has sent the switch ctrl message, the dongle will then reappear but this time with the 05c6:0016 id.

It may be that iBall has used a different switch message than the one used for a previous dongle with the same default id, it has happened before and especially for devices with a Qualcomm vendor id.

Please upload your windows sniff log here so I can see what makes it switch.

[D3m0N81]

I've attached the USBSnoop.log for the action iBall3..5G is plugged in. Also other files which I though might help.

You have a typo in your config file, f1000 should be f000 .

I'll check your snoop file and oemxxx.inf files.

[LOM]

Your usbsnoop files did not relieve anything, did you log 05c6:f000?
You may have to uninstall the windows drivers and the connection manager and disable cd autorun, then replug the dongle which then should show up with its initial id 05c6:f000 and remain so without switching.
Then start logging 05c6:f000 and execute the autorun script on the dongles cd-rom, it will log the whole install of drivers and connection manager. The log will stop to get filled when Windows switches the dongle to 05c6:0016, one of the last messages in the log will be the switch message.

Your screenshot and the 2 .inf files shows the following interface layout:

MI_00 Diagnostics
MI_01 Application (AT cmd interface)
MI_02 Voice
MI_03 ???
MI_04 Modem
MI_05 Storage


Seeing that the storage interface is not 0 but 5 in 05c6:f000 where there is only one interface makes me suspect that the following might work:

sudo usb_modeswitch -W -I -v 05c6 -p f000 -i 5 -M 55534243123456780000000000000601000000000000000000000000000000

[D3m0N81]

I'm sorry for the typo & invalid usb_modeswitch run.

I ran the cmd with suggested message:

That was a much better log, it shows that the dongle switches by the cd-rom eject cmd (URB 1351, one of the last cmds in the log).

You can test it on the cmd line by:

usb_modeswitch -W -I -v 05c6 -p f000 -V 05c6 -P 0016 -M 5553424312345678000000000000061b000000000000000000000000000000

or by doing an eject of the cd-rom device, ie eject /dev/sr1


If the ctrl msg above works (it should) then the only thing you need to do in order for the dongle to switch after
reboot or hotplugging is to edit the current usb_modeswitch device config file 05c6:f000 and replace the line
TargetProduct= 0x9000
with
TargetProductList= "0016, 9000"

The 05c6:0016 usb id is not directly supported by the option.ko serial driver so you'll have to add on-the-fly support for it
after the option driver is loaded.

sudo modprobe usb_wwan
sudo modprobe option

and then

echo "05C6 0016" > /sys/bus/usb-serial/drivers/option1/new_id

This should give you ttyUSB0...ttyUSB4 where ttyUSB4 is the modem device.

I tried yesterday with other messages extracted from log dump using below cmd, it wasn't working. Perhaps -i 5 was the cause...
usb_modeswitch -W -I -v 05c6 -p f000 -i 5 -M xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

3. modprobe usb_wwan; modprobe option; echo "05C6 0016" > /sys/bus/usb-serial/drivers/option1/new_id

and I got [ttyUSB0 .. ttyUSB2] and ttyUSB2 was for data.
I was able to connect to Internet.

Will make necessary changes to config & dialup script.

Once again thank you.

Thanks for the lsusb listing, it explains why you got the modem on ttyUSB2.
iBall has disabled interface 2 and 3 in the dongle, interfaces which if enabled would had created ttyUSB devices.

Script I'm using to connect after plug in:

to be run in root session:

Code: Select all

#!/bin/bash
usb_modeswitch -W -n -I -v 05c6 -p f000 -V 05c6 -P 0016 -M 55534243e0793c88000000000000061b000000020000000000000000000000 > /dev/null 2>&1
modprobe usb_wwan
modprobe option
echo 05C6 0016 > /sys/bus/usb-serial/drivers/option1/new_id

It takes [5..15] seconds to connect and I've enabled 'Connect automatically'.

Any sane reason to disable it?

Another query, how to deduce from the capture log that a switch happened?

Usually, at the end of the log there is a "SURPRISE_REMOVAL" if you caught the right device ID. This is the moment when the switch happened. The action that initiates the mode switch is not far from the log's end.

The excerpt that you quote is a well known switching action, transmitting the SCSI EJECT command to the dongle.
