A lot of pictures of the official Wiikey 2 installation guides and results from other people's hardwork show that a Wiikey sort of fits in the hole of the "donut" looking green circuit board.

For instance, here's one showing it placed on the "gray stuff".


Is one susposed to use a hot-glue gun and glue the chip there? Or perhaps I'm missing something obvious like a clip or something where it stays still.

Any thoughts? Thank you.
