The Oracle Device Driver Utility (DDU) reports whether the current release supports the devices that have been detected on your installed system.
The Device Driver Utility provides information about the devices on your installed system and the drivers that manage those devices. The DDU reports whether the currently booted operating system has drivers for all of the devices that are detected in your system. If a device does not have a driver attached, the Device Driver Utility recommends a driver package to install.
You can also use the Device Driver Utility to submit your system information to the HCL at https://www.oracle.com/webfolder/technetwork/hcl/index.html. Your system and its components are then listed on the HCL as “Reported to Work”.
