I actually found an article in Polar's website. The site from Finland times out and the graphics on the US site don't load.

The pages on the USB drivers from both sites time out and the link to customer service doesn't work. Can you tell how fabulous I think Polar is?

However, the device manager shows that the interface is fine when not attached to the hub.
