Try the cable in a different usb slot. if that doesnt work, just for fun, try the cable with a different device. It could be a bad cable, rare but it happens. You could also stop by your local Big Lots, Wal-Mart or Dollar Store and pick up another cable . It will work fine and a whole lot less expensive. High price cables are usually a rip-off. Chargers are a little trickier. But a usb cable is a usb cable ! Just my 2 cents !
