ENODEV Operation not supported by device seems better in this context than "Device not configured". The device is configured (it's attached and configured)- it's just not ready for operation. Usually this is an EIO error, but if you're going to have other than that, I believe ENXIO is misleading. On Mon, 7 Sep 1998, Kenneth D.
