Has anybody encountered something like this? I have, sort of. I've got a USB drive enclosure with a USB cable. The two of them together don't work on my home PC. Replace any one of the components (computer, enclosure, or cable) and the result works. Try to figure that one out! It certainly sounds like the hub/ethernet adapter combination isn't working right. Have you tried moving them to a different computer? Or have you tried using the D-Link device with a different hub?
