driver not attached Message

The following driver-related message may be displayed by the prtconf and sysdef commands:

device, instance #number (driver not attached)

This message does not always mean that a driver is unavailable for this device. It means that no driver is currently attached to the device instance because there is no device at this node or the device is not in use. Drivers are loaded automatically when the device is accessed and unloaded when the device is not in use.
