## NAME

**#include \<sys/bus.h\>**

## DESCRIPTION

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**().
