Human Interface Device protocol setups accommodate keyboards, headsets, microphones, mice, gaming controls and more. Some describe it as a plug-and-play technology that bypasses some of the more complex driver protocols, although driver necessities may apply. For example, many USB keyboards that are external can now be plugged in to a wide spectrum of devices through a completely standardized USB port in order to allow for human input.

Downsides of the Human Interface Device protocol include the need to establish legitimacy of devices and the ability of hackers to introduce malware and other problems through USB devices.
