Abstract
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.
