Problems solved by technology

[0013] This problem can be avoided or alleviated to a certain extent by using a high-speed CPU, but the CPU required at this time is very expensive
In addition, when the system control circuit of AV equipment etc. is composed of a microcomputer, the price of the CPU in the whole is also important, and if it is expensive, it cannot be adopted even if it is fast.

Embodiment Construction

[0021] The equipment management method and management system of the present invention will be described below with reference to the accompanying drawings.

[0022] Such as figure 1 As shown, in the currently used Linux (registered trademark), when the USB (UniversalSerial Bus) device is hot-plugged and connected, no matter what device is connected, once the USB mass storage device is connected to the personal computer, then as figure 1 As shown in a, the hotplug script hotplug is called by extending the processing of the probe function probe in the core driver usbcore prepared in the kernel space KERNEL.

[0023] The present invention focuses on this point and utilizes the hotplug script hotplug to realize hotplug processing. Below, refer to figure 2 The hot-plug processing when a mass storage device is connected to a USB on a personal computer loaded with Kernel 2.4Linux (registered trademark) will be described.

[0024] The present invention and the above figure 1 Like ...

Abstract

This invention is a method of managing a device, which performs a hot-plug function in the device (peripheral device) in a non-event-driven OS (Operating System). A hot-plug script hotplug is called by a core driver usbcore of a kernel when the device is connected or disconnected. When called, the hot-plug script hotplug performs predetermined processes described in it, and then calls a hook program hooker. When called, the hook program hooker executes a hot-plug manager pnpmanager, thereby acquiring information about the device.

Description

technical field [0001] The present invention relates to a device management method and a management system, which are used to realize the hot plug function of devices (peripheral devices) in a non-event-driven OS (Operating System, operating system). [0002] This patent application is based on Japanese Patent Application No. 2003-060889 filed in Japan on March 7, 2003, claims priority, and is incorporated by reference in this patent application. Background technique [0003] Some of the AV (Audio and Visual) devices can be used in combination with a personal computer, and some can input and output audio data and video data through a network. A multitasking OS is generally used in a personal computer connected to such AV equipment. [0004] On the other hand, in an event-driven OS such as Microsoft Windows (registered trademark), the user application program is configured such that it executes corresponding processing such as starting, terminating, and drawing graphics afte...
