Hi,
The items marked VEN_1B73&DEV_1100 are the drivers for the Fresco Logic USB hub inside your D5000 dock. These are needed for the rest of the dock to function. These are supplied by the dock installation package - please see this URL for more information:

This recommends installing the software first and then connecting the dock.
Thanks,
James
