Method for driving multiple universal serial bus equipments

Abstract

The invention relates to a method of driving a plurality of USB devices, which belongs to the field of computer technology. The USB device is configured with communication rules and the communication rules are searched by a main frame driver module according to information, such as manufacturer code, and the like, from a management module, thus obtaining the serial number of the device; the request instruction of data interaction from a main frame application module is processed by packing treatment and sent to a current plug-in device; the plug-in device carries out the packing treatment for data from the main frame driver module and sends response information back to the main frame driver module; the main frame driver module unpacks the received response information according to the communication rules to obtain the valid data, and the valid data is sent to the main frame application module; and when the device is removed from the main frame, the main frame driver module clears out the communication rules of the corresponding device. The method of the invention has the advantage that as long as the configuration method of the USB communication rules is grasped, the new USB device can be supported more quickly and more reliably.

Description

technical field [0001] The invention relates to a method for driving multiple universal serial bus devices, which belongs to the technical field of computers. Background technique [0002] Currently on the market, there are mainly the following technologies for driver management when multiple Universal Serial Bus devices coexist: [0003] 1. Install the drivers of each Universal Serial Bus device separately, and use and manage them independently after installation, but there may be conflicts during the installation and use, and it is inconvenient to use and operate, especially the development of upper-layer applications based on the bottom-level drivers. more complex and difficult to maintain; [0004] 2. Package each driver in a unified way, and then provide a unified application interface. When a universal serial bus device is plugged in, the system will find and install the driver that meets the universal serial bus device, but for the driver that is not included in the ...

Problems solved by technology

[0003] 1. Install the drivers of each Universal Serial Bus device separately, and use and manage them independently after installation, but there may be conflicts during the installation and use, and it is inconvenient to use and operate, especially the development of upper-layer applications based on the bottom-level drivers. more complex and difficult to maintain;

[0004] 2. Package each driver in a unified way, and then provide a unified application interface. When a universal serial bus device is plugged in, the system will find and install the driver that meets the universal serial bus device, but for the driver that is not included in the package The system still cannot recognize and use the corresponding universal serial bus device, which leads to the limitation of supported universal serial bus device drivers. Once there is a new universal serial bus device that needs to be supported, the program needs to be repackaged or re-modified , although the ease of use has been improved, but the maintenance cost is relatively high, and frequent packaging and modification of the program will also bring risks such as instability;

[0005] 3. Write a new driver to support the existing Universal Serial Bus device, integrate the source code of each Universal Serial Bus device driver, and the driver executes different program branches according to the characteristics of each Universal Serial Bus device , so as to achieve unity in form, but this scheme has the same problem as scheme 2, that is, when there is a new universal serial bus device that needs to be supported, the driver also needs to be modified, which is not easy to expand, and is not conducive to ensuring stability
