Embodiment Construction

[0010] The present invention relates to systems and methods for updating device drivers resident on a host device as part of a firmware upgrade process. In particular, peripheral devices include firmware that is upgraded to a new or different version. During the upgrade process, the host computer automatically checks its currently installed device drivers to determine if they are compatible with the upgraded firmware. If the current device drivers on the host are compatible, the host simply communicates with the peripheral using these installed device drivers. If not compatible, the host automatically replaces the outdated device driver with an upgraded device driver stored in the memory of the peripheral device.

[0011] figure 1 A system 10 suitable for use with one embodiment of the invention is shown. System 10 includes peripheral device 20 and host device 40 . Generally, peripheral device 20 is connected to and operates under the control of host device 40 . In this e...

Abstract

A host (40) connects to a peripheral device (20) having upgraded firmware (34). The host (40) also includes a device driver (46) to communicate with the peripheral device (20). If the device drivers (46) currently installed on the host (40) are not compatible with the upgraded firmware (34), upgraded device drivers (32) are automatically downloaded to the host (40) from the peripheral device (20).Once installed on the host (40), the peripheral device (20) is reset and the upgraded device drivers (32) are used to communicate with the peripheral device (20).

Description

[0001] related application [0002] This application claims the benefit of U.S. Provisional Patent Application 60 / 944,227, filed June 15, 2007, and this application is co-pending U.S. Application No. 11 / 564,553, filed November 29, 2006 and August 15, 2007 Continuation-in-Part of US Patent Application 11 / 838930 filed on . The '227 application, the '553 application and the '930 application are incorporated herein by reference. Background technique [0003] The present invention relates generally to peripheral devices, and more particularly to systems and methods for updating device drivers associated with these peripheral devices. [0004] Some host devices, such as laptop computers, can communicate with wireless networks using plug-in peripheral devices, often called "PC Cards." A PC card can be connected to a computer via a Universal Serial Bus (USB) connection, and the PC card includes a radio frequency (RF) transceiver and an integrated antenna. Although performance gener...
