For now, I will do this.

For the later option, I advice you to install the latest version of libusbx

For now I'll put this to my TODO list.

My code started working when I did 'uninstall' the complete python and all
its packages. Then I have installed plain Python(2.7.3) and Pyusb(1.0.0a4),
and as you can see the code its working right *after* switching the
backend( *usb.backend.libusb0.get_backend() *).

If you suggest me some minor experiment I can do that.

Thanks and Regards
Vivek

PS: Sorry for the delayed response, I missed this last response.
