; This application is meant to demonstrate a framework for an
; application running on the 68HC908JW32. It demonstrates a simple HID
; interface for a USB device and uses interrupts from the USB
; peripheral. The HID interface is supported through standard API calls
; in Windows® XP, Windows® 2000, or Windows Vista™ Operating Systems.
; For more information on USB, visit the USB
; developers website at www.usb.org and download the USB specification
; revision 2.0 and the HID device class specification version 1.1 for
; more details.
