USB Accessories Disabled

I try to sync my Polar Vantage V with Polar FlowSync but when I plug the USB cable I get the message: "Unplug the accessory using too much power to re-enable USB devices." It is the same message for the all USB ports on my MacBook. What is the problem? What can I do to solve this?
