Most examples have a 1M pull-down resistor at D+. This pull-up ensures that
in self-powered
AND, I only seen pull-up res in D- in schs provided in that folder...

The pull-up on D- is 1.5k and identifies the device as low-speed. The 1M pull-down is only needed if the device should work stand-alone (without connection to the USB host). Most examples are bus-powered and therefore won't work without host anyway.
