A kind of usb device and usb communication method

Abstract

The invention discloses USB equipment. The USB equipment comprises an interactive input module, a controller and a USB output interface; the controller comprises a signal transmission port; the controller is used for receiving control information and monitoring a control instruction sent by a computer terminal through the signal transmission port; the working state of the USB equipment is configured according to the control information or the control instruction; the controller is also used for creating an equipment state instruction in a USB data format according to the working state of the USB equipment and sending the equipment state instruction to the computer terminal through the signal transmission port so that the computer terminal can synchronously record the working state of the USB equipment. The invention furthermore discloses a USB communication method. Through the USB equipment and the USB communication method, a user can operate on the USB equipment and control the working state of the USB equipment on the computer terminal, and operation trouble is avoided.

Description

technical field [0001] The invention relates to the field of universal serial bus, in particular to a USB peripheral device. Background technique [0002] USB (Universal Serial Bus, Universal Serial Bus) is a serial bus standard that connects computer systems and external devices. Higher data transfer rates are achieved, such as video data at higher resolutions and higher frame rates. [0003] Thanks to the rapid development of USB technology, the functions of some peripheral devices with USB transmission capabilities that need to transmit images and videos are also becoming more and more perfect, such as video booths, high-speed cameras, etc. However, in the existing technology, video booths, high-speed cameras, etc. cannot directly transmit extended functional data such as human-computer interaction data. The zoom-in or zoom-out operation can only be realized by operating the upstream device connected to the video booth - a host such as a tablet or a computer, but not di...

Problems solved by technology

However, in the existing technology, video booths, high-speed cameras, etc. cannot directly transmit extended functional data such as human-computer interaction data. The zoom-in or zoom-out operation can only be realized by operating the upstream device connected to the video booth - a host such as a tablet or a computer, but not directly on the video booth, which will cause trouble in operation; in addition, it cannot be done on a computer terminal Control the working status of the USB device, such as turning on or off the fill light, adjusting the projection angle, etc.
