Dedicated circuit and method for enumerating and operating a peripheral device on a universal serial bus

The invention relates generally to devices and methods for communicating between a host computer and a peripheral device such as a keyboard or mouse and, more particularly, to recognizing and enumerating a peripheral device as a compliant Universal Serial Bus (USB) device and for performing other USB functions by using a micro-controller and a USB dedicated circuit interchangeably. A circuit for a use in a control system of a peripheral device that is dedicated to tasks related to communication with a host computer via a universal serial bus (USB). The invention affords a USB dedicated circuit that is configured to allow a host computer to recognize and enumerate a device as a USB configured device without the use of the device's micro-controller. In another aspect of the invention a USB dedicated circuit that is configured to perform other USB related tasks in conjunction with the device's micro-controller in a more efficient manner than a device operating solely with a micro-controller.
