I have read many forum i found that there is no compatibility of USB with PIC 18F452
but when i see example program there is some awesome thing or this my mis_interpretation that PIC 18f452 support USB protocol but there is no D+ & D- PIN in PIC 18F452
Code:
/////////////////////////////////////////////////////////////////////////
//// ////
//// ex_usb_serial.c ////
//// ////
#if __USB_PIC_PERIF__
#include <18F4550.h>
#use delay(clock=48000000)
#else //use the National USBN960x peripheral
#include <18F452.h>
#use delay(clock=20000000)
#endif //endif check to see which peripheral to use

Code mostly removed.

Note the line:
"//use the National USBN960x peripheral"
This is the 452, talking to USB, _with a separate interface chip_.
Also, remove the code you have posted, since you are in breach of the copyright:
"No other use, reproduction or distribution is permitted without written permission."
You can simply refer _to _ the library by name here, since everybody already has the compiler files if they own the compiler. Posting the files though is _illegal_.
