Query: Did great .....until it broke

Easy set up, worked great, for a little while. After a very short period, it just stopped working. Maybe it was just the one I bought, but I was very unhappy, especially since a fight ensued about who was going to replace it(Still unresolved)An update: After several months of arguing about whether the failure was software or a hardware issue, Microsoft finally agreed to replace the adapter. Of course I had already bought another from a different company, and they wouldn't simply refund the purchase price. The one I have works fine, so I haven't installed the replacement adapter and can't say if it works any better.
