Do you mean in Device Manager? If so, the barcode readers should show as installed devices in Device manager. If you don't see them listed, expand the USB listing in device manager and they should appear.

If thay are not listed there, then they may have their own catagory under input devices or something like that. You need to expand the entry list in Device Manager to see the individual devices.
