Discussing with other friends i found that there are Adapters available in the market which coverts a SMD/PLCC package into a DIL.

Yes - they are well-known and have been frequently mentioned on this forum;
eg, http://www.8052.com/forumchat/read/179931

But one of the reasons that DIP is now obsolete is because of the problems caused by the long lead lengths - and that's only going to be worse with these adaptors.

And, of course, you still have to solder the devices onto the adaptor. If you're happy doing that (or getting that done), what's the problem with soldering them directly onto your own board??!

Which controller you ppl suggest to try and check the USB operation through microcontroller.

Judging from your performance here, and previous threads about basic UART use, I wouldn't recommend that you jump in to USB development any time soon. I think you need to spend more time honing your basic skills before moving on to advanced topics like USB...
