USB simple app PIC18F2550/4550

[pasini]

I have a simple prototype similar to the USB PIC DEMO board, with a PIC18F2550/5V. I want to simply write/read a byte from the USB interface, and use HiperTerminal (or a serial-like COMM port in a Windows XP application). The borad has a 2 LEDs and a potentiometer that are working fine, and I included the 2 resistors in PIN_B2 to detect attachment of the device to the computer.
I want to use the bootloader to update firmware. Do I need to include the following code ?

#build(reset=0x1, interrupt=0x5) // Necessary for Bootloader
#org 0x0800,0x0FFF // Necessary for Bootloader

What files should I add and modify ( pic18_usb.h, usb.h etc) Should I modify them according to my app ?

I am using MPLAB 7.20 + CCS 3.23

Thanks in advance,
Pasini

How does my board inform Windows which device driver it must use to receive data from the USB interface ?
