It installs the software for Hewlett-Packard 6511-SU USB Internet Keyboards. These keyboards have 15 hotkeys (inc Standby), media controls (stop/play/etc.), and a volume KNOB instead of buttons. The keyboard also has a built-in USB 2.0 2-port hub (ports located at each end of keyboard). The keyboard was designed for Windows 98 but it works fine on Windows XP Pro if using this software. Supposedly this software also works for model 5308, but I can't back that up.
This utility (NOT A DRIVER, keyboard functions without it) allows you to configure the hotkeys and on-screen display (for when you push a button).
The settings can be accessed by going to Keyboard in Control Panel and selecting the Buttons tab.
