Query: Keyboard not found at startup!

I bought this product a couple of years ago and it works intermittently. The wireless connection is not acknowleged by your computer when it initially boots. Once you use a usb keyboard to bypass this stage and Windows stats only then is your keyboard recognized.Support? This consists of playing email tennis with logitech until you decide you've had enough. They will get you to try everything except direct you to a service agent. Go for it if you like a gamble.
