The red one is the driver for my huawei usb pen modem .

Because it is USB the correct device should be
/dev/ttyUSB0 instead of /dev/ttyS0

bash-3.2#
Code:
grep -B5 'ttyUSB' /tmp/bootkernel.log

Till date I'm looking in all wrong places.
Thank you Karl for your little eye opener.
You said "It should "ttyUSB0" instead of "ttyS0".
Yessssss!!!! thats the answer.
In my case it's "ttyACM0" and its showing in top of the Internet connection wizard.
I never noticed it, what a fool!?!
