; This module declares the descriptors

;

; This example has one Device Descriptor with:

;	One Configuration - single IN port and single OUT port

;	One Interface - there is only one method of accessing the ports

;	One HID Descriptor - to make PC host software simpler

;	One Endpoint Descriptor - for HID Input Reports

;	One Report Descriptor - one byte IN and one byte OUT reports

;	Multiple Sting Descriptors - to aid the user

;
