Each device has an enabled flag associated with it. A device is
enabled by default when it is created but may be disabled (for instance to
prevent a destructive or time consuming probe attempt). To disable a device,
call
device_disable
(),
to re-enable it, call
device_enable
()
and to test to see if a device is enabled, call
device_is_enabled
().
