* specify the length of vendor-specific CDBs the target expects and
* should normally be set to 0. On successful completion
* of enable, the specified target instance will answer selection.
* Disable causes the target instance to abort any outstanding commands
* and stop accepting new ones. The aborted CCBs will be returned to
* the user via read(2) or discarded if the user closes the device.
* The user can then re-enable the device for a new path.
