Problems solved by technology

[0003] However, due to historical reasons, the compatibility of the Linux operating system is not particularly good
When a USB device is connected to a computer running on the Linux operating system, although the operating system kernel (Kernel) can detect the insertion or removal of the USB device, the application program cannot get these messages, that is to say, the kernel and There is a lack of pipelines between applications, which requires manual user intervention to select and configure USB devices when using applications
[0004] In contrast to the functions provided by the Windows operating system, after Windows 2000, the detection function for USB ...

Embodiment Construction

[0042] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0043] The present invention provides a method for plug-and-play to USB devices under the Linux operating system, by establishing a daemon process (Process) between the system core and the application program, so that the application program can know the connection situation of the USB device in real time, such as figure 1 As shown, the method includes: storing a plurality of USB device drivers and generating a list of devices (step 101); setting corresponding configuration files (step 102) for USB device support; obtaining the USB device interface from the Linux system kernel according to the configuration files Enter the message (step 103); analyze the message and identify the brand of the access device (step 104); read the internal information of the device to obtain its model (step 105); according to the device brand and model in the syst...

Abstract

The present invention provides plug-and-play method for USB equipment under Linux operation system. First, several USB equipment drive programs are stored and one equipment list is created; then, corresponding configuration file is set, USB equipment access message is obtained from the system kernel based on the configuration file, the brand of the equipment is analyzed and distinguished, the equipment type number is read out and the equipment drive program is searched; and finally, the drive program is loaded automatically and the specific information of the equipment is informed to the application program. The present invention establishes relationship between the Linux operation system and the application program to makes it possible for the application program to understand the USB equipment inserting and removing information timely without need of user's intervention.

Description

technical field [0001] The invention relates to a plug-and-play method for a USB device, in particular to a plug-and-play method for a USB device under a Linux operating system. Background technique [0002] At present, with the popularity of the Linux operating system, more and more individuals and industries use Linux, and more and more applications are developed for Linux. On the other hand, Universal Serial Bus (Universal Serial Bus, USB) is as a new generation of peripheral device interface, because its transfer rate is much faster than the parallel port or serial port used by personal computers, for computer equipment and The transmission efficiency of the peripheral interface has been significantly improved, so it has been widely used once it is launched on the market. [0003] However, due to historical reasons, the compatibility of the Linux operating system is not particularly good. When a USB device is connected to a computer running on the Linux operating syste...
