 It is being detected as a pseudo SCSI CD-ROM device, hence no
 /dev/ttyUSB* devices.

 Not the same modem, but, still relevant:
 http://oozie.fm.interia.pl/pro/huawei-e220/


Thanks a lot for the link.  But still there is some problem.

I copied the files from above and did necessary modifications(the vendor and
product ids) and put them in place.  So, now, when I boot with the USB modem
plugged in, the kernel modules get loaded.  But, I couldn't find
/dev/ttyUSBx.

These are the files I copied and modified from the above link :
/etc/udev/rules.d/99-huawei.rules and  /lib/udev/huawei-mobile.sh  (both
these files are attached)

When I insert the USB modem after booting also the same case :

And I did :

sudo udevcontrol reload_rules

and

sudo modprobe -v usbserial vendor=0x12d1 product=0x1411

But still, dmesg shows

I am still missing something.  What is that ?

 If the block device block size is what you want then the command is

blockdev --getsize64 /dev/hda1

 Here the answer is also in bytes for the device /dev/hda1. Note that
 block-devices usually (always?) work with a sector size of 512-bytes.

Did you mean blockdev --getbsz /dev/hda1 ?

Here is another trick.  Don't know if it will always work.

echo a  test
du -h test

Sorry, I didn't notice that you have written device block size.
