upjeeper, from what I know, from the community, an external HDD USB MUST be plugged into the port closest to the edge (port 0) or the Wii can't find it. I had a cheep hub, non-powered, jacked into the other plug (port 1). Works perfect for ethernet and microphone. I switched them one once for giggles. The HDD could not be found. Hopes this helps, BUT be careful about trying it with a powered USB hub. Best bet is keep searching.
