Basically a composite device is any hardware component that is designed to perform more than one task like a multimedia keyboard or a multifunctional mouse. In most instances these types of hardware components fall under the classification of Human Interface Devices since most of them are used by the computer user to directly interact with the host computer system. In this instance the Bloomberg USB Composite Device makes use of the Universal Serial Bus interface port to implement its multifunctional capability. The device driver makes sure that the Universal Serial Bus interface port where the hardware component is plugged in can effectively support it. In many cases newer composite devices cannot be supported by older computer system that make use of the version 1.1 of the Universal Serial Bus. However, if the device driver has been designed for backward compatibility then it is possible to deploy this hardware component in virtually every type of computing environment.
Unless you update your drivers regularly you may face hardware performance issues.
To check your drivers you should manually verify every device on your system for driver updates
Technically mice are the best examples of composite devices. This is because they not only keep track of the computer user's movement but also provide buttons that activate specific functionalities. However in general composite devices are those which are commonly regarded as having more than two different types of input functionality. In this context the most common example of a composite device is a game controller that plugs into the Universal Serial Bus interface port of the host computer system. Usually a composite device like the Bloomberg USB Composite Device makes use of a different interrupt for every interface that it has. The device driver communicates with the host operating system platform in order to ensure that an interrupt is assigned to both the input and the output processes of the supported hardware component. The device driver may also be partly responsible for the execution of a Universal Serial Bus compliance test. It is highly recommended you run a free registry scan for and Bloomberg USB Composite Device errors before installing any driver updates.
