Sansa clip keeps disconnecting

If what you have is similar to the item you linked to, it isn’t a USB 1 port. It’s a USB 3.0 Card Reader and 3 Ports USB Hub, High Speed External Memory Card Reader. And that means your USB port is a USB 3.0, or that device wouldn’t work. It also means your USB port should be capable of having your Clip connected to it with a standard cable that has the same specs as the original cable supplied with it when you bought it. You can easily identify a USB 3.0 post by the plastic tab inside the connector. If it is light blue, it’s a 3.0. If it is white it’s either a USB 1.0 or 2.0.
