3.2.4 ESD Considerations

Hosts require an additional degree of robustness when it comes to ESD protection on data lines and VBUS, as multiple, unknown, and potentially dubious devices can be causing ESD events downstream. Typically, a higher ESD rating is recommended, around 8kV contact and 15kV air.
