In computing, the USB human interface device class (USB HID class) is a part of the USB specification for computer peripherals: it specifies a device class (a type of computer hardware) for human interface devices such as keyboards, mice, touchscreen, game controllers and alphanumeric display devices. The USB HID class is defined in a number of ...
USB3 Vision [1] is an interface standard introduced in 2013 for industrial cameras. [2] It describes a specification on top of the USB standard, with a particular focus on supporting high-performance cameras based on USB 3.0. [3] It is recognized as one of the fastest growing machine vision camera standards. [4]
Unlike USB 2.0 and USB 3.x, it does not provide a way to transfer data directly, it is rather a mere container that can contain multiple virtual connections ("tunnels"). Other specifications are referenced to define the contents and internal functionality of a tunnel. USB4 defines the following tunnel types: USB3 connections; DisplayPort ...
The idle line state is when the device is connected to the host with a pull-up on either D+ (for full speed USB 1.x) or D− (for low speed USB 1.x), with transmitter output on both host and device is set to high impedance (hi-Z) (disconnected output). A USB device pulls one of the data lines high with a 1.5 kΩ resistor.

The caret, text cursor or insertion point represents the point of the user interface where the focus is located. It represents the object that will be used as the default subject of user-initiated commands such as writing text, starting a selection or a copy-paste operation through the keyboard.
A USB network relies on a single host at the top of the tree to control the network. All communications are between the host and one peripheral. In a FireWire network, any capable node can control the network. USB runs with a 5 V power line, while FireWire supplies 12 V and theoretically can supply up to 30 V.
The USB video device class (also USB video class or UVC) is a USB device class that describes devices capable of streaming video like webcams, digital camcorders, transcoders, analog video converters and still-image cameras. The latest revision of the USB video class specification carries the version number 1.5 and was defined by the USB ...
