/usr/sbin/makedev [-f]
The makedev(1) utility creates all standard device special files supported by Interix. the device files are created in the /dev directory; any existing files in that directory or any subdirectories with names that conflict with the standard special file names are removed and replaced with the appropriate device files.
You must be logged on as a member of the Administrators group to run makedev(1), otherwise the utility displays an error message and exits.
Interix recognizes the files created by mknod(1) as unique. Superficially identical files created through means other than mknod(1), mknod(2), and makedev(1) (for example, through backup and restore) will not be treated as device files by Interix, and attempts to open devices through such files with fail with the error code ENXIO.
If the standard device special files become corrupted for any reason, the makedev(1) utility will recreate them in such a way that Interix will recognize them as valid. Any additional (that is, nonstandard) device files created by users must be recreated using mknod(1) or mknod(2).
You also use makedev in the unlikely situation that the inode security file has been damaged. If it has, all existing device special files are invalidated and must be recreated. (The information returned concerning them by the ls -l command remains correct, but they will not be recognized as valid by open(2). The command makedev -f should be used under these circumstances, and if device special files have been created elsewhere on the file system, those files also must be be refreshed manually.
The makedev utility accepts this option:mknod(1)
mknod(1)
