Why doesn the Device–>Select Class command work?
This is usually because the “device type” and “qualifier type” that were selected don’t both match a device in the system. For example, selecting a type of “Disk” and a qualifier of “SCSI” will not select any devices because SCSI disks use qualifiers of “Hard, Floppy, etc.” Use the Device–>Current Device Status command to determine the valid type and qualifier that apply to a specific device.
