OK, I waited for the latest round of updates, esp the cumulative update to win10. I performed the update, rebooted with the new kb and no change - still not working. I attached the old kb to enter my password so I could boot, reattached the new kb and did another update using touch screen. Voila', "hardware update required", which I did. On restart my sp3 recognized the new kb and I am now good-to-go. Hope this helps someone. I love the smaller, more separated keys, and the improved type feel. It is a much improved keyboard over the old one.
