Value-added Input Drivers
In earlier versions of the Microsoft Windows NT operating system, it was a common practice for vendors to replace built-in system input drivers with their own value-added versions. Under Microsoft Windows 2000 and Windows XP, this practice is no longer valid--setup will fail with the error logged in %windir%/setuperr.log.
For Windows 2000 and Windows XP:
NOTE: To include directives from an original system INF, you should use Include and Needs directives in the [DDInstall] section of the device INF. These directives allow a third-party INF to include standard setup directives for its device without copying and pasting these directives from the original system INF files. The use of Include and Needs directives also allows Windows 2000 to change the way a port or class driver is set up and to have all third-party INF files automatically incorporate this change.
