    'This version is written using Visual Basic 2005 Express Edition, Beta 2, available from:
    ' http://lab.msdn.microsoft.com/express
    'This version does not compile and run on earlier editions of Visual Studio.

    'Purpose: 
    'Demonstrates USB communications with a generic HID-class device

    'Description:
    'Finds an attached device that matches the vendor and product IDs in the form's 
    'text boxes.
    'Retrieves the device's capabilities.
    'Sends and requests HID reports.

    'Uses RegisterDeviceNotification() and WM_DEVICE_CHANGE messages
    'to detect when a device is attached or removed.
    'RegisterDeviceNotification doesn't work under Windows 98 (not sure why).

    'A list box displays the data sent and received,
    'along with error and status messages.

    'Combo boxes select data to send, and 1-time or timed, periodic transfers.

    'You can change the size of the host's Input report buffer and request to use control
    'transfers only to exchange Input and Output reports.
