A disclosed gaming machine is coupled to a plurality of 'USB gaming peripherals.' The USB gaming peripherals, which may include one or more peripheral devices, communicate with a master gaming controller using a USB communication architecture. The USB gaming peripherals may include USB DFU (Device Firmware Upgrade)-compatible peripheral devices. One or more host processes, such as a USB device class manager or a DFU driver, may be capable of downloading firmware to the USB DFU-compatible peripheral device. The host processes may receive a firmware identifier from the USB DFU-compatible peripheral device where the firmware identifier allows for two USB DFU-compatible peripheral devices with identical product identification information to be downloaded different firmware.

Download procedures for peripheral devices

A disclosed gaming machine is coupled to a plurality of 'USB gaming peripherals.' The USB gaming peripherals, which may include one or more peripheral devices, communicate with a master gaming controller using a USB communication architecture. The USB communication architecture may include a vendor-specific class protocol. The USB vendor-specific class protocol may comprise: 1) a base protocol for defining message handling relating to peripheral device functionality common to a plurality of peripheral devices; and 2) one or more feature-specific protocol extensions for defining message handling specific to a USB feature where each feature-specific protocol extension defines feature-specific messages. The base protocol may be designed such that when one of the feature-specific messages is modified, the base protocol does not change.

Protocols and standards for USB peripheral communications

A disclosed gaming machine has a plurality of 'gaming peripherals,' each communicating with a master gaming controller via a standard peripheral interface such as the USB (Universal Serial Bus).). For USB compatible communications, characteristics of a USB gaming peripheral class are defined. The USB gaming peripheral class allows features of a USB gaming peripheral in the USB gaming peripheral class to be controlled by a USB host in a manner compatible with USB.
