There are four types of USB transmission. The basic data transmission modes include control transmission, isochronous transmission, interrupt transmission and data block transmission. Each transmission mode is applied to terminals with the same name and has different properties.
Control transmission type: Supports the transmission of control, status, configuration and other information between the peripheral and the host, and provides a control channel between the peripheral and the host. Each peripheral supports the control transfer type so that configuration and command/status information can be transferred between the host and the peripheral.
Isochronous transmission type: Supports data transmission between peripherals and the host with periodicity, limited time delay and bandwidth, and constant data transmission rate. This type of error-free check cannot guarantee correct data transmission. It supports data transmission such as computer-telephone integration system (CTI) and audio system and host.
Interrupt transmission type: support input devices such as gamepads, mice and keyboards. The data transmission between these devices and the host is small and non-periodical, but they are sensitive to response time and require immediate response.
Data block (batch) transmission type: support peripherals such as printers, scanners, digital cameras, etc. These peripherals and the host transmit a large amount of data, and USB can only perform this type of data transmission when the bandwidth is satisfied.
Different USB transmission types require different USB interfaces to adapt.
