I would like to design a small usb keyboard with custom keys(UP,DOWN,RIGHT,LEFT) which can be used as game controllers. How keystrokes are recognized by PC through Usb. Which micro controller can perform this action.
 

I personally think developing PS2 keyboard will be more easier..cheaper and faster

Indeed it will, even a small 8-pin micro could do it. However, whilst most desktops still support PS2, few laptops still do. I have seen the software AVR-USB (can't remember what they're calling it now..) which can emulate a USB PC keyboard using the native windows drivers. As for custom keys, you may have to write your own application for that.
