Abstract

Disclosed are a universal serial bus (USB) drive method, computer and composite device. After a computer and a composite device establish a connection, the computer transmits a descriptor acquisition command to the composite device; the computer receives a preset single-interface descriptor transmitted by the composite device; according to the obtained single-interface descriptor, the computer determines that the composite device is a single-interface device, and loads a preset user-defined drive. The computer of the present invention by not starting the composite device drive in a composite device enumeration process simplifies the composite device enumeration process performed by the computer, and improves enumeration efficiency. On the other hand, the computer of the present invention by not starting the composite device for enumeration, can also reduce the error rate in the development and maintenance of the device drive of the composite device, thus solving the problems of high costs and low efficiency of the development and production of the composite device.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a driving method of a universal serial bus, a computer and a composite device. Background technique [0002] The enumeration method for multi-interface Universal Serial Bus (USB, UniversalSerialBus) devices (i.e. composite devices) is roughly as follows: the composite device is inserted into a computer (computer), the computer obtains the descriptor of the composite device, and parses the descriptor, The computer composite device driver loads the driver program corresponding to each interface according to each interface of the composite device. Among them, the composite device driver is at the kernel layer of the computer, and undertakes a lot of work during the enumeration process of the composite device. Developers need computers to drive composite devices in multiple links such as R&D, testing, production, and after-sales of composite devices. However, the kernel codes of s...
