    AHKHID - An AHK implementation of the HID functions.
    AHKHID Example 1
    Last updated: August 22nd, 2010
    
    List all the HID devices connected to the computer.
    This example shows how to use all the AHKHID_GetDev functions (like AHKHID_GetDevInfo()).
    _________________________________________________
    1. Simply run the script.
    2. Press Ctrl+c on a selected item to copy its name.
