INPUT/OUTPUT (I/O) DEVICE CONFIGURATION SIGNATURE

摘要

A method for building a configuration signature for an input/output (I/O) device is described herein. The configuration signature is built based on descriptors of an I/O device and save to a host after an initial connection. After the initial connection, the I/O device may be subjected to modifications. To determine if such modifications exist, the descriptors of the I/O device are compared to the configuration signature after the initial connection.

1. A method, comprising:
reading descriptors of an input/output (I/O) device at a host; building a configuration signature from the descriptors in response to a connection between the I/O device and the host; and comparing the descriptors of the I/O device to the configuration signature to determine if a modification to the I/O device has occurred after an initial connection of the I/O device to the host.
