Hi Edison,
we should start again.
You are using ubuntu 12?
Is it right, that your kernel-version is 3.2.0-30 ?
(uname -a )
I am not sure, but in this case you can forget qmi and you can focus on
"option".
In your first mail usb-switch did work correctly.
you should see 2357:f000 directly after plug in
and you should work with 2357:9000.
If " option" doesn't load, then load it via modprobe and
echo "2357 9000"> /sys/bus/usb-serial/drivers/option1/new_id
Then try to use Network/Modemmanager to connect via /dev/ttyUSB0.
Regards,
Thomas
