SYSTEM, METHOD, AND DEVICE INCLUDING BUILT-IN SELF TESTS FOR COMMUNICATION BUS DEVICE
First Claim
1. A device comprising:
- a communication interface operable to be coupled to a communication bus of an information handling system;
a configuration descriptor stored within a memory operable to be accessed during a communication bus scan; and
a self-test descriptor associated with the configuration descriptor, the self-test descriptor operable to be read in association with the configuration descriptor.

Abstract
A method, device, and system including built-in self tests for a communication bus device is disclosed. In one form, a method of testing a device operable to be coupled to a communication port an information handling system includes accessing a configuration descriptor of a first device operable to be coupled to a communication bus of an information handling system. The method can also include detecting a self-test descriptor associated with the configuration descriptor and testing a portion of the first device using test information associated with the self-test descriptor. The device and system can include logic to perform the methods described herein.
