The Host device check option loads a utility (shown below) for accessing details related to the peripherals attached to the host system.

This utility can be useful when trying to determine the device path of physical devices.  For example, when connecting a physical disk to a virtual machine.  It is also useful for discovering the SCSI path details when configuring a GK type object.

This utility can filter output by device class.  It can also display and save the information shown in the table as a text file by using the Open and Save As... buttons, respectively.
