Then it should return ENXIO ("no such device or address"), not ENODEV ("no
such device"). The distinction is subtle, but
- ENODEV means "there is no driver to handle that device node"
- ENXIO means "the driver exists, but the device does not"
- EIO means "the device exists, but we had trouble using it"
