Query: Does not work

I am a very knowledgable network engineer and I could not get this device to be recognized by the Vista OS on my laptop, I checked everything from the switch to the print server and it all worked fine. When I plug in the print server to the working circuit, the port light shows activity but the server is not recognized. Nothing helped so I ordered a 50" USB cable.This box is a waste of time.
