I just went through this installing the "Creator's" update.
The Serial I/O is a key ingredient, but if you are upgrading it will show as already being installed. Repairing does not do the trick -- you need to uninstall the old version, restart, and then install fresh and restart again. Then the trackpad will appear after restarting.
Thanks to everyone who contributed to this thread!
