Abstract
A computing system detects an input/output (I/O) device configuration error. The computing system includes at least one I/O device installed with firmware configured to control an I/O function, and a plurality of I/O ports installed on the at least one I/O device. At least one I/O port outputs a request to perform a current I/O configuration initialization and generates current I/O configuration data corresponding to the current I/O configuration initialization. A memory unit is configured to store the current I/O configuration data and previously generated I/O configuration data. The I/O device compares the current I/O configuration data to the previously generated I/O configuration data, and detects the I/O device configuration error in response to determining a mismatch between the current I/O configuration data and the previously generated I/O configuration data.
