Schematic

Typical connection of USB-Slave-Connector

When choosing a protective-diode circuit (D1), choose one that has not got an internal pull-up!
If the USB-Slave is used for debugging-purpose only or if you need to reduce part-count, the reset-generator logic could be removed. Leave the voltage divider and maybe include a capacitor for signal-debounce.
