1. Introduction
The Silicon Laboratories CP2110/4 is a USB device that adheres to the USB-defined Human Interface Device
class specification. HIDs communicate with a USB host through the use of reports. This document is a specification
for the reports supported by the CP2110/4 and it also describes the configurable parameters.
Silicon Laboratories provides dynamic libraries that adhere to this specification for the following operating systems:
