Abstract: A method and apparatus for configuring multiple devices in a computer system is presented. Upon receipt of a device enumeration request corresponding to a first device, an indication that the first device is inoperable is returned. In response to a second device enumeration request corresponding to a second device, an indication of the capabilities of the second device is returned. When a configuration command corresponding to the second device is received, configuration information derived based on the configuration command is provided to both the first and second devices such that uniform parameter configuration is achieved with respect to the first and second devices. Because the operating system that issues the device enumeration request is informed that the first device is inoperable, the first device will be rendered unconfigurable and therefore configuration commands addressed to the first device will not be generated by the operating system.
