device_enable, device_disable, device_is_enabled — manipulate device enabled flag
#include <sys/param.h> #include <sys/bus.h> void device_enable(device_t dev); void device_disable(device_t dev); int device_is_enabled(device_t dev);
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().
