Please see the delay between (1) and (2)... Any idea about the reason for the delay. Though I am not sure, it may not be specific to Linux kernel version.

Dear Oliver,
Thanks for your response. I tried with 3.10.1. As you rightly pointed out, it does not seem to work on my board (pandaboard). It gets stuck at "Starting kernel...".
Now, I am trying with 3.4.47 version now. Let me see if it works. The delay of creating /dev/dvb/adapter0/frontend0 and /dev/dvb/adapter0/demux0 seems to exists. I am waiting for it to get created.
I am downloading 3.4.54 and 3.10.2 now.
Regards,
Kishore.

Your kernel is ancient. The latest kernel with the latest media fluff is 3.10.2; Since you are on arm, chances are your platform isn't that well supported with later kernels, but even in the 3.4 world your kernel is ancient. Latest stable is 3.4.54.
So you are asking for help, with something that could have been fixed 3 times over (or not, I don't know). So my first suggestion is to upgrade your kernel. If that's not possible on your arm platform, contact the supplier of your kernel.
Meanwhile, since this is an USB device, you could try it on a desktop.
Get a recent Ubuntu live CD and see if it works there. At least then you can quickly and easily see if your problem hasn't been fixed in the last year.
