The command that is executed at boot time to discover and configure attached devices
is cfmgr. After booting the system, if a device is either removed/powered-off or
attached/powered-on, the state of the device in the ODM is not automatically changed.
Rather than running mkdev or rmdev on the specific device, you would typically execute
cfgmgr. cfgmgr would discover any new devices or re-assesses the state of any
devices already defined in the ODM customized device database.
