I have an ipod shuffle that I want to hook up to an emac. The shuffle won't fit into the emac's recessed USB plug, so I need an adapter. RadioShack sells a cheap extender for about $6 (which ir eally just a short piece of plastic about an inch long with a USB A plug on one side & USB B on the other) that would work, but it doesn't say if the adapter is USB 2.0 or just USB 1. Is there a difference in extenders between 1.0 & 2.0 USB or would both work the same
