USB communications device class (or USB CDC) is a composite Universal Serial Bus device class. The communications device class is used for computer networking devices akin to a network card , providing an interface for transmitting Ethernet or ATM frames onto some physical media.
WinUSB is a generic USB driver provided by Microsoft, for their operating systems starting with Windows Vista but which is also available for Windows XP. It is aimed at simple devices that are accessed by only one application at a time (for example instruments like weather stations, devices that only need a diagnostic connection or for firmware upgrades).
For isochronous devices like audio streams, the bandwidth is constant and reserved exclusively for a given device. The bus bandwidth therefore only has an effect on the number of channels that can be sent at a time, not the speed or latency of the transmission. Low speed (LS) rate of 1.5 Mbit/s is defined by USB 1.0. It is very similar to full ...
Universal Serial Bus 4 (USB4), sometimes erroneously referred to as USB 4.0, is the most recent technical specification of the USB (Universal Serial Bus) data communication standard. The USB Implementers Forum originally announced USB4 in 2019. USB4 enables multiple devices to dynamically share a single high-speed data link.
A Universal Serial Bus, or a USB is an industry standard communication protocol used to communicate data across connectors, and cables from computers to peripheral devices and/or other computers. [4] WebUSB is a set of API calls that enable access to these hardware devices from web pages.
The Universal Serial Bus was developed to simplify and improve the interface between personal computers and peripheral devices, such as cell phones, computer accessories, and monitors, when compared with previously existing standard or ad hoc proprietary interfaces.

In May 2018, Synopsys demonstrated the first USB 3.2 Gen 2x2 operation mode, where a Windows PC was connected to a storage device, reaching an average data rate of 1600 MB/s for reading bulk transmissions, [71] [72] which is 66% of its raw throughput. USB 3.2 is supported with the default Windows 10 USB drivers and in Linux kernels 4.18 and ...
