This is one of those product that looks great on paper but is cheaply made and very flimsy. The hub connects, then disconnects repeatedly. It seems either the cable, the connector or the circuit board is loose and I have to turn the thing around, or press on the connector, and hold to it with my hand before it connects.The Compact Disk slot is flimsy and does not always take the card unless you twist and jam it in.The CD that came with it had a completely different driver on it, for a IDE drive enclosure. Strange.
