Can anyone tell me where I can find basics of USB.
I have gone to its website, but I found their documents bit hard to understand.
Any other website or AN giving detailed & tutorial wise explanation of USB & interfacing with MCU

Hi, get a hold of Jan Axelson's Book on USB, it it simply THE most usefull resource discussing USB I have ever found, after that try to get familiar with the USB protocol readily available on the web free of charge. After that try to build a keyboard using the HID driver.

I have taken these steps and they were very helpfull in following projects, I recomend to stay away as much as you can from custom drivers, almost any small non-data aquisition project can be fitted in the HID drivers and are already suported by most mayor OS's including the newest smart phones OS's

Happy reading!!!!

I have 3rd edition of Axelson's USB Complete. It is a great book but if you just want to interface USB to MCU, fastest route is to either get MCU with USB or add USB support to your MCU using FTDI chip for example. FTDI requires no programming unless you want to store your own ID into it and drivers are ready for any OS. to both computer and MCU, this looks like a good old RS232 port. For example check following:
