You will need a data cable and not just a generic Mini USB cable.
Surely a generic cable is a data cable. A power-only cable is quite a specialist item.
I don't know about newer types, but there is definitely a difference for mini USB. Three people on this page alone (four if it is the same issue for the OP) have said they have first hand experience of the issue.
