Features
The Happ 3" Trackball with USB & PS/2 interface allows personal computers to easily interface with the standard "Arcade Quality" trackball and pushbuttons from the Happ via either the USB port or PS/2 connector without the use of any external power supply. This allows the user to replace the existing mouse with a Happ heavy-duty trackball for public access and similar applications. The USB & PS/2 trackball can be added with or without removing the original mouse. The device will be automatically configured as soon as it is physically plugged into the USB port or hub, without the need to reboot or run Setup.
