microchip PIC18,pic24系列单片机USB驱动的开发源码

// File: BootModified.18f4550.lkr
// Sample linker script for the PIC18F4550 processor

// This linker is modified for use by the HID Bootloader when using the PIC18F4550
// microcontroller.  This linker should be included in the HID bootloader
// firmware.  A separate linker should be used by the application that will 
// be loaded by the bootloader.
