1. A device comprising:
- a communication interface configured 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 configured to be read in association with the configuration descriptor, and configured to enable the information handling system to test a portion of the device using test information associated with the self-test 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.

7. A method of testing an electronic device, the method comprising:
-
accessing a configuration descriptor of a first device coupled to a communication bus of an information handling system; detecting a self-test descriptor associated with the configuration descriptor; parsing the self-test descriptor and the configuration descriptor; and testing a portion of the first device using test information associated with the self-test descriptor after parsing the self-test descriptor and the configuration descriptor. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. An information handling system comprising:
-
a communication bus configured to couple the information handling system to a bus-enabled device; a processor in communication with the communication bus, the processor configured to initiate a scan of the communication bus, to detect the bus-enabled device, to send a request to read a configuration descriptor of the bus-enabled device, to parse the configuration descriptor and a self-test descriptor associated with the configuration descriptor; and a test mode output in communication with the communication bus, the test mode output configured to be coupled to the bus-enabled device in response to parsing the configuration descriptor and the self-test descriptor, and further configured to test a portion of the bus-enabled device using information associated with the self test descriptor. - View Dependent Claims (16, 17, 18, 19)
