Patent ID: 8880747

Claim:
An endpoint device discovery system, comprising: an information handling system (IHS) chassis; a downstream port that is located in the IHS chassis; a register that is located in the IHS chassis and that is coupled to the downstream port, wherein an endpoint ready status bit is configured to be set in the register in direct response to an endpoint ready message that is received at the downstream port from an endpoint device that is coupled to the downstream port and that has experienced a power-on or reset operation; and a non-transitory computer-readable medium that is located in the IHS chassis, that is coupled to the register, and that comprises computer-readable instructions that, when executed by a processor that is located in the IHS chassis, prevent the processor from attempting to communicate with the endpoint device following the power on or reset operation until the processor determines that the endpoint ready status bit has been set in direct response to receiving the endpoint ready message from the endpoint device and, in direct response to determining that the endpoint ready status bit has been set in direct response to receiving the endpoint ready message from the endpoint device, cause the processor to automatically access and configure the endpoint device.
